Sunday. Summer. And a few familiar questions.
1. when you're using tomtom, what happens when you want to make a call or get a call?
You can answer the call, but the GPS will stop if you use a Bluetooth headset
2. Can you use a bluetooth headset while the gps is running?
Yes, but the GPS will not communicate with the Treo
3. Are some GPS recivers better than others? (i.e. better signal, fast sat pick up ..)
Yes, look for SIRFIII.
Answers to 1 and 2 might have changed with the Treo 700p and TT6, but I'm not so sure.
