Just a long shot here but I'm wondering if anyone knows anything or even better yet could point me in the direction to a diagram for the tomtom V3 gps. The USB plug broke off the motherboard, I have soldered it back on however something still isnt right cause it wont charge or even connect with my pc now.

Not a whole lot of chance you will find schematics or diagrams on an item like that.

It used to be, way back in the day, manufacturerss actually made this kind of stuff available. Now it is all proprietary.. And, all about money. Basically, you shouldn't be able to fix it, because you need to buy a new one!

Just get yourself a continuity meter, and follow the traces on the board from the USB plug to wherever they connect. See if you have a connection between the two points. You're probably just missing a connection there. You may have created a very fine crack in the board also during the break.

Hi shucky
I can't speak specifically on the TT V3, but the following link shows the basic pinout connections used by a lot of manufacturers for mini USB

This may help (even if only by a process of elimination)
I have also seen charging problems resolved by grounding both pins 4 and 5.......but this must be at your own risk!
