My 920T connects with my Blackberry 8830 just fine for in/out calls handsfree through the TomTom, but the voice quality from my end is weak. I've tried to connect the 920T through my Jawbone but no success. 920T finds it and tries to connect, but when the password is input (0000) it fails to connect with that password. I've checked my Jawbone lit and the password is correct. I've also unpaired with the phone before trying to pair with the TomTom. It works fine with my Blackberry. Any suggestions as to how to get it to work or is there a different headset that is more compatible?
