I recently dug an old Navman S35 out of the basement, and was attempting to get it working when it started showing non existent roads and no new roads. so i went to plug it into my laptop (Dell Inspiron 1525, T9300 ect.) and downloaded the appropriate software. but, however, the software works fine whenever the GPS is NOT plugged in, but whenever it is plugged in, it freezes the application and I have to exit it with task manager. is there any solution to this issue or is it because its a new OS with crappy backwards compatibility?
