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

[Guest takashi2]

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.
