xda and Com1 does not exist

Can any body Help? Seem to be running tomtom fine on my xda but when you tell it to connect though COM1 it tells you that the port does not exist. So you try it on COM2 and it just becomes so slow and crashes. Have tied all the other connections but don't seem to work. Thanks Simon

sihodge there have been alot of posts regarding this problem, you need to disable IR, click on start, settings, connections, beam and untick the box

when you go into tomtom select Tom Tom Navigator GPS, serial cable com 1

Thanks, it seems to have solved the problem.
