TomTom 720 and the TP

[lcutts]

I have the traffice plan through TomTom services. I was able to bluetooth my phone to the device and can do hands-free calls and transfer my phone book. I cannot however, receive traffic services. I get a red screen on the 720 stating I don't have a data connection. I have a Sprint data plan that worked great with the device before I upgraded from a PPC 6700. I was wondering, has anyone managed to find a fix for this. Hope I don't have to upgrade my Nav device.
