For those out there that are looking for a phone and uses Sprint and that is 100% bluetooth compatible with their '05 TL w/NAVI look into the MOTO KRZR KM1. I bought the phone and it works great with the car. Though the phone itself may not be up to standards (reading forums on the phone on various web sites), it works great with tha car. The sound comming out in the car is good. People tell me that the sound quality is good on the other end as well. You have both battery and signal strengths. Call waiting and being able to transfer your call works great.

 

Thanks for the heads up.

We already have a few phone threads running on this forum:
