I have an x51v and use tomtom with a wired gps receiver. I had to change the name tofix the problem I was having with TT5 and the Dell wired gps on my Axim X51v. Found This on another board:
The problem is due to the corrupted serial driver name in the registry, that is why you see "Se???a?? ?a??d?? st?? COM1: " in Tom Tom GPS menu.
1. Use a registry editor, e.g. PHM Registry Editor v0.70

2. Locate HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Serial
3. You will see the value name "FriendlyName" has some Russian characters for the value data
4. Change that to Serial Cable on COM1:
5. Make sure you exit registry editor from Tools -> Exit, that will save the changes properly.
6. Now go to Tom Tom and your wired GPS should be working. You may need to do a soft reset if Tom Tom is still not picking up your wired GPS.
Heres what I set my settings to in TT5(should be the same for all us dell wired gps + tt5 users): In TomTom 5 go to Show GPS Status: Select Other NMEA GPS, GPS baud rate:4800, choose Serial Cable on COM1. That should do it. give it a few seconds and it should see the satellites.
Hope this helps you!
