[Guide] Fix for Tom Tom (tomtom) GPS COM port problem on Samsung GT-B7610 with WM 6.5

I made many tests with the solutions proposed on many forums. At the end I found the most simple working solutions on my Samsung OmniaPRO GT-B7610.
On board:
- Windows Mobile 6.5 (WM 6.5) [CSC_B7610NXXIL4.csc - Phone_B7610XXJC1.bin - PDA_B7610NXXJC2_HW_70.MST]
- tom tom Navigator 7.918.9193 (part 1, part 2) / 7.917.9186

To be sure that everything will be fine, I suggest to make first an Hard Reset of your device to avoid COM ports “old” conflicts.

1- On your dial pad digit *#1472365#, that will open an hidden function "Nogarder GPS"
2- Menu -> Settings -> GPS
3- Starting: set on “Cold Start (Delete All)”
4- OK –> Exit
5- Switch off and on (NOT Soft reset!!!)
6- On your device: Start -> Settings -> Network -> GPS –> Connection
7- Set “GPS software port” on COM4, “Hardware GPS port” on COM9, “Baund rate” on 9600.
8- Install Tom Tom Navigator (the last are 7.918.9193 and 7.917.9186)
9- In tom tom settings: Change preferences -> Configure GPS - Configure
10- Select “Built-in GPS receiver”.
11- Wait for the fix.

[Update #1]
It seems that after using ActiveSync, the previous configuration doesn't work anymore! So, use the next working configuration:

1- Idem
2- Idem
3- Idem
4- Idem
5- Idem
6- Idem
7- Set “GPS software port” on COM8, “Hardware GPS port” on COM9, “Baud rate” on 9600.
8- Idem
9- Idem
10- Select “Other NMEA GPS receiver”, “GPS baud rate”: 4800, tap on COM8
11- Idem.

[Update #2]
If the GPS signal is good, tom tom needs just (about) 1 minute and 30 seconds to fix. If for any reason tom tom needs MORE than 3 min make this:

1- On your dial pad digit again *#1472365#, that will open an hidden function "Nogarder GPS"
2- Menu -> Get Position
3- Wait for the fix (often fast)
4- DON'T press OK
5- Press "End/Power" key (DON'T switch off your device)
6- Launch tom tom and wait for the fix
7- If you want, you can go back and close the "Nogarder GPS" hidden funciton

OR:

1- On your dial pad digit again *#1472365#, that will open an hidden function "Nogarder GPS"
2- Menu -> Settings -> GPS
3- Don't do anything! Just ceck if “Cold Start (Delete All)” is selected
4- OK –> Exit
5- Switch off and on (NOT Soft reset!!!)
6- Launch tom tom and wait about 1 minute and 30 seconds to fix

[Update #3]

After having used the previous methods, it seems that re-selecting again "Hot start" [instead of “Cold Start (Delete All)”] in "Nogarder GPS", maks the GPS fix faster!

If something goes wrong and/or you made many changes and/or you don't want another hard reset, I suggest to use "OmniaGpsModkey":

1- Install GpsModDriver, launch it and select Yes [when you tap on No, you reset the default keys];
2- On your device: Start -> Settings -> Network -> GPS –> Connection;
3- Set “GPS software port” on COM4, “Hardware GPS port” on COM9, “Baund rate” on 57600;
4- Soft reset;
5- In tom tom settings: Change preferences -> Configure GPS - Configure, select “Built-in GPS receiver”.

Notes
- After the fix you can increase both the Baud Rate in Phone Network settings and in tom tom GPS settings.
- I suppose this guide applies to Omnia I8000 too.
