I'm wondering if anyone has successfully been able to share their phone's data connection with their GPS. I have enabled Bluetooth tethering, but unfortunately the GPS says "This feature not supported", so I am unable to login to TomTom Services or get any updates while on the road. I have no idea whether this is a problem with my phone's OS or simply the TomTom device has compatibility issues with my device. I just find it hard to believe that Bluetooth configurations would be that much different between devices.
