Is there a spot to connect a external antenna like on tytn at the back?
No there is not.

Are you sure?
Its usually hidden somewhere in the battery compartment under a sticker or label or rubber plug. It might even be under the battery its self.
What is very strange i found it in one phone under a lable saying Void if removed...
Very odd considering the plug while not public common use. Is a perfectly viable antenna connection and often used in rigs, car phones and business.
But most phones have them.
Yes, this doesn't.
thnx for the info guys. hmmm this might change my descion to get it. unless it has better reception then i get with my Tytn i wont be able to get reception without it.
This is an issue for me too, as I just found this:
http://www.easydevices.co.uk/products.asp?partno=TCANTENNATPRO&model=
Says it's an external GPS antenna for the HTC Touch Pro...
Or would this work?
http://www.mobilefun.co.uk/product/10939.htm?referer=FR_PROD-PR-P-10939
The first thing is discontinued, obviously because they found out (probably by some angry buyers) that TP DOES NOT have a GPS plug.
The second is a full BT GPS device. Works with any BT enabled computer or PDA (inc. the TP).
GPS Antenna
I was also disappointed that there was no BT antenna available.
I was seaching some GPS antenna maker hoping to find some that could use existing MiniUSB port on TP but it seems the port is unable to support communication with GPS software.
So sad, this would have been a good enhancement to TP if there was MiniUSB GPS antenna maker.
Guys do you know what you are talking about?
I suppose not.
BT or USB are not "generic I do it all" technologies. They work based on specific protocols.
A GPS antenna is usually passive equipment - and even for active ones we mean that something amplifies the received signal.
THAT signal (and in fact the whole antenna), is "stupid". It is the part of the chipset to receive the ELECTRICAL data and make them into usable data.
I am not sure if I am getting through, my English are not the best, but the point is that you are looking in the wrong place for the wrong thing.
Now if you want a real USB or BT GPS that you will use instead of the internal ones, that's a whole different story. This works and actually does it by using the "COM" (serial) support that both USB and BT include.
To make the story more complete though, USB solutions will not work for devices that don't support "USB-host" (i.e. being the host part not the client part of the connection). Most WM don't have this (and yes Diamond and TP also don't). So you are left with BT.
To be honest if you are ready to pay for that premium (and you seem to be, by the links you give), what is your problem if what you connected is a full GPS that "replaces" the internal one or not?
I hope everything is more clear.
I presently use a TyTN II, and have an external aerial as the mount for the device is under a metal dash, so shields the signal...
I therefore need an external receiver for GPS.
Se here: http://freespace.virgin.net/shaw.clan/modifications.html and click on the TomTom hiolder link, although this is with the older QTEC 9100.
Make sense?
For driving with my Garmin in the car i used a Re-Radiating in my Xterra with excellent results.
This is basically the setup I have, although the internal antenna wasn't integrated into the power plug.

Mine is a bit more similar to this so you can control where you mount the internal antenna.

I have yet to test it on the Fuze but will probably do it when I have time this weekend. The change in signal strength is drastic (on the garmin).
Woow insanely expensive!

Hi Guys,
This is a reference thread for anybody who has patchy reception and is considering using an external antenna to boost reception.
I have found that the patch cable required is the same as most other samsung phones.
The particular cable I used is this one: http://www.cellink.com.au/productde...=1&pcr=WES0830&tsb=Samsung&tsm=Omnia+2+(i8000)
I imagine that the same type of product would exist overseas as well - but if you are in a tight squeeze Cellink distribute worldwide.
Note that plugging in this cable disables the internal antenna (so if you don't have an antenna plugged to the other side of the patch cable then you will lose reception immediately).
Finally note that YOU WILL HAVE TO REMOVE THE BATTERY COVER TO USE THE PATCH CABLE. I'm hoping to get a second cover and drill a hole in it so that I can simply plug the cable in through the whole. I can confirm that there is enough clearance to drill a hole and plug the cable in that way.
Let me know if you have any questions.
I quite like the idea, but I have a few concerns:
Does the antenna work for both internet (all networks), wifi, gps, and normal cell connectivity?
Would one theoretically be able to connect an RP-SMA antenna, I have some nice wifi antennas lying around
I have read some concerns about the manual switch responsible for turning the internal antenna on / off is not that reliable and can cause issues stopping your internal antennas from working
Hi fed44,

Would one theoretically be able to connect an RP-SMA antenna, I have some nice wifi antennas lying around I'm not an expert here but from my limited knowledge: (1) you would need some kind of patch cable because the standard patch cable outputs to a male SMA connector (and not an RP-SMA) and, (2) there appear to be different antennas for different purposes (wifi, mobile network, etc.) my understanding is that a wifi antenna is not optimal for boosting mobile signal - that said it may or may not provide a boost over the internal antenna.
I have read some concerns about the manual switch responsible for turning the internal antenna on / off is not that reliable and can cause issues stopping your internal antennas from working I think this is an issue with older samsung phones. I have experienced no such issue with my external antenna (over around 10 uses). I'm not sure but I don't think it actually uses a manual switch - the reason why I say this is because when you unplug the antenna it takes a few seconds to switch back to the internal antenna.

I was thinking about using something like that. My problem is that 3G signal is very weak in two places where I spend most of the time - home and work. And for some reason phone is preffering 3G even if signal is so weak that internet is not working. So I had to turn off 3G. But it seems stupid to have HSDPA capable phone using EDGE only.

I can confirm that this setup will be awesome for that.
I haven't drilled the hole yet (in the case that is) - but once I do that it will make the setup much more functional.
Im doing some smuggling business in my country, Android tablets are very popular, and I get good price difference when buying in China and selling in my country.
First time - I bought FT2 (Superpad, Infotmicx220) and 2 units were faulty.
second time - I bought FR-809's and one unit was broken.
so, I was trying to fix it on my own, and opened the unit (no screws version, dual speaker) and it was bad soldering. the battery/SoC connection was off, so I fixed it.
now the tablet works, but I already sold all other units, so I want to experiment.
One of my broken Superpads is with internal GPS receiver, no need for GPS Antenna. so, Idea struck me - could it be possible to solder GPS unit onto the Freescale SoC .. ?
Android would handle the reception, it's all there, I just need to figure out if it's possible, and if there is even an option to solder GPS receiver onto SoC ?
that internal receiver from Superpad is awesome, and it would be awesome if I could have GPS on my FR-809 tablet.
could someone please tell me is there a "free slot" for soldering stuff. like a PCI bus on motherboards ? and, would system be able to recognize the newly soldered GPS receiver ?
anyone ?
Im also thinking about soldering SIM slot onto it, at least for 3G cause i believe it needs a whole lots of other stuff for GSM function to be enabled (voice radio, n such)
i got this px5 KGL (erisin) for my sisters mercades b200
man this is terrible.. now i understand what people were complaining about..
when BT is connected to phone the wifi is useless!!
my KSP unit does not have this..
i have already soldered an external wifi antenna, but it does not help at all!!
how r people coping with that?
i am already on latest MCU 2.54..
I hear you buddy, I have a KGL as well upgraded from px3 to px5 board, and also soldered a proper wifi antenna.
In my experience, if wifi is connected (tethering phone data for example) I am unable to pair the phone using Bluetooth.
I normally turn off the wifi on the head unit pair the BT and then turn on the wifi again.
The drawback is that whenever bluetooth is paired, wifi does not transfer faster than about 3 Mbps.
The moment I turn wifi off, the wifi speed improves absurdly
I am evaluating the possibility of replacing the wifi + bt chip...

It is one chip for both.. it is surface mounted.. good luck changing that..
May be an external Wi-Fi dongle of some soft. I do believe back in mtcb units they had succeeded going that road
i looked into this. the surface mounted chip is an usb interface connected device.
http://www.realtek.com/products/productsView.aspx?Langid=1&PFid=59&Level=5&Conn=4&ProdID=373
if it is a usb device one could try to desolder it and put an usb port there instead. and then connect a usb dongle with the same chip externally...

but honestly i doubt it will fix this.
btw. do you have this buzzing/humming sound in the spekers when using bluetooth handsfree? with the actual malaysk rom i cannot do one call i can hear nothing and peaopletelling me it sounds like a helicopter.
with HA rom it works 90%.
i haven't hooked up this unit to the car yet

I have been brainstorming for a few days when I have had a chance to check how this chip could be replaced. While yes, it is surface mounted, it has its own circuit board which is then soldered to the main board. The module looks like this:

Packages are similar (QFN 56 pins) so there should be modules built from these as well.

I do hear the noise as well, running Malaysk too, it has not been as rough in my experience, mostly only noticeable when the car is stationary. I did have to change the mic because it sounded like I was in a construction zone, lots of random noises during calls.
today i removed the antenna from my device entirely.
absolutely no difference. ist seems the antenna is not connected to the wifi chip which would perfectly explain why we have this bad wifi reception....
did a check on spareparts on aliexpress. found the following
https://www.aliexpress.com/item/RTL8723BU-USB-Interface-WIFI-BT-Wireless-internet-MID-GPS-Bluetooth-WIFI-wireless-module/32466684026.html
there are some specs listed in the most detailed form i could find yet.
bullet 5 describes how an antenna for the chip should be built.

could the missing condensers be the issue?
im not that into high fequency electronics. but i think i remember condenser in line is a hipass-filter...
maybe there are some low frequencys interfering with the chip?
i removed the BT cable antenna completely and it made no difference.. i thought that might reduce the impact, but interference is the same. useless.. i am returning the stupid KGL thing.. absolutely crap
I have the same problem and decided to apply a simple solution.
The issue is produced for interference between wifi and bluetooth signals. They are in near frequencies and hardware doesn't have enougth protection.
So, I decided to turn wifi off anytime I must use bt for a phone call. All interferences completely dissapear and phone conversation is clear both sides of the line.
Hi, i found a solution for the problem. I bought a USB wifi+BT dongle and i connected to the rear usb port of the unit. By restarting the system the bluetooth and wifi starting work again.

Comfast wu725b is said to work with these units and will override the built in module. Just search for it on Ali or eBay. Or search for wifi bt dongle and look for it. My phone wont let me copy the link at the moment for some reason

As i have understood it, it will override the bt automatically and still let you use the built in wifi if you want, but you can also use the dongles wifi module if wanted

I've had similar problems with a KGL MTCD/MTCE unit (2GB RAM, PX5, with MTCD MCU). The problem isn't the ROM, but for reference, I'm running Malaysk's latest PX5 ROM. Most notably, I experience significant break-up using bluetooth for calls. Additionally, I'm unable to pick up WiFi from inside my house out in my driveway, though various phones and laptops can do this acceptably well.
We opened the unit, found bad soldering at the WiFi/Bluetooth module, and attempted to repair it. We replaced the antenna with an SMA pigtail and longer antenna, and removed a soldered short in the board. We then powered back up with the new antenna, and found the signal no better, and in fact possibly worse than before (we may have damaged something when trying to fix the module).
We also noted that there is a small antenna printed on the bottom side of the board. There were several problems with this. First, the "internal" antenna was "connected" (more on that in a second) to RF1. RF1 on the specs for this module as published by a number of sellers on AliExpress shows RF1 as being no contact. So, we're not even sure how that's supposed to work. Second, I said "connected" before, because the soldering was bad and apparently didn't really have a connection at all. Third, being an antenna on the underside of the board inside a metal case will probably preclude it from working at all anyway.
The biggest problem is likely metal under the dash of my car, which prevents WiFi from being picked up well under there. The antenna needs to be moved out from under the dash.
I considered getting an SMA extension cable to simply move the antenna. However, at the end of the day, I've ordered a USB module, in the hopes of getting it to work. The module is listed as "USB WiFi Bluetooth Adapter, Wireless WiFi Dongle Network Adapter 150Mbps & Bluetooth Transmitter Receiver with External Antenna for Desktop/Laptop/PC, Supports Windows 7/8/8.1/10/XP/Vista/Android" and sold by "iFun4U" on Amazon.com. The unit has a larger antenna than the Comfast unit previously mentioned, and appears to use the same Realtek RTL8723BU chipset that the onboard module uses (typo'd in the listing as "Realteck TRL7823BU"). Here's a link to it: https://www.amazon.com/gp/product/B01JYE5BT2
My hope is that by plugging this unit in and restarting the system, the wireless kernel module will pick up the external USB device first and register it as wlan0, making any further configuration unnecessary. If that fails, I'll look into ways to specifically assign my external device as wlan0. Worst-case, I'll open my unit back up and de-solder the USB data pins on the module.
I'll let you know how it goes.
Update -- on my KGL unit, simply plugging in the new WiFi/Bluetooth dongle caused the system to crash when booting. We ultimately had to disable the onboard Realtek chip by cutting the power trace to the board. After that, the system boots right up, and the Wifi works quite well.
wondering if this also means A2DP audio streaming is clear now too?

Please check the post earlier in this thread by GeorgeM269, which shows pictures of the pinout for the board. To be honest, if you cannot use those to determine the pinout of the board, I do not recommend you attempt to cut a trace. You could destroy your head unit, and I accept no liability for that. Do this at your own risk.
- If you have opened the unit, and are looking top-down into the unit, with the face-plate on the top side, and the back panel on the bottom side.
- From that angle, on what I'll call the left-side of the small board, you'll see 4 connections, which are GND, RF0, RF1, CLK. RF0 runs to the antenna connection on the board.
- On what I'll call the bottom edge of the board, there are 6 contacts which have have no connection.
- On what I'll call the right edge of the board, there are 4 connections which represent a USB connection to the system. From top to bottom, these are GND, Data+, Data-, PWR (3.3V). The 3.3V power connection, on the bottom right of the board, is the one we cut.
- Check your results with a meter to be sure you've fully cut through the trace.
For what it's worth, this mod is still working without issues.
I'm not sure what "antes USB hub" is. I can tell you there are no issues with using the USB hub I purchased. Personally, I ended up plugging my USB WiFi/BT dongle onto one of the ports on the rear of the head unit.

I ordered this USB stick off eBay Link. It has the RTL8821CU chipset with Bluetooth 4.2, wifi ac standard, and 5ghz Frequency. The radio does pick it up as a USB device but it doesn't have a driver built into the kernel. I'm going to see if I can build a kernel module and get it to load. Just a little hesitant to try because if it causes the kernel to crash i'll have to lose my settings/info to restore it as I don't have ADB set up yet.
