Treo 650 (Sprint) Hands free in a Saab 9.5

[BEW]

I would like to get a bluetooth hands free phone set up in my car. I was intially hot on the Parrot CK3000 evolution, but then talked to an installer who told me Saab has an amplified system and the radio mute etc. would not work and told me save my money. Does anyone have another sugestion. How about the Parrot easy drive or the Motorola HF 800 that clips to your visor. Thanks.
