Thank you for the information! After I installed Tomtom first and
then the widcomm stack everything works fine! I didn't changed anything in my registry...for the first usage I connected to my BT GPS mouse (i-Blue747) and selected the service SPP Slave. Then I started Tomtom6 and selected there "another bluetooth gps mouse" and I think it was Bluetooth COM8. And everything works, I dont even have to start bluetooth now before Tomtom. I only power on the GPS Mouse and start Tomtom, Tomtom itself powers on Bluetooth and connects automatically to the GPS mouse.
