I would appreicate learning anything that you may find out. I also just bought a RX350, but could not get my Treo 650 to connect. The phone said then connection was succesful, but the SUV did not. The dealer attributed it to the phone, saying they could not figure out why mine and other Treo's had this problem.
I just got a Lexus RX 350 and I was able to connect my Verizon Treo 650 with my car via bluetooth but the connection gets dropped after about 15 seconds. Any ideas about how to solve this problem??
