Bluetooth
actually, the reason they aren't 100% compatible is because the Treo is Windows based and that's where the problem lies.
I tried the Treo p, wx, all of them and no luck...Went to almost every blackberry and finally ended up with the curve and it's perfect and so were all of them.
But Treo's are terrible with the car.
Throw it away.
I have a Palm Treo 700p and Sprint is my wireless carrier. My car is an '07 GS430. I received a text message on July 31 from Sprint indicating that there was a firmware upgrade just released for the Treo. The text message contained a link (see below) and the upgrade specifically addresses issues with Bluetooth compatibility with Toyota/Lexus (Denso) and BMW and the Palm Treo.
They are now directly compatible and work well together. I find that the Palm Treo is a decent phone...at least in my opinion. I think it was just a compatibility issue between Palm and Denso.

Treo 755p (Sprint) compatibility with other Bluetooth devices
Solution ID : 44829
The Treo 755p smartphone is a Bluetooth Qualified product. This means it has passed the Bluetooth Special Interest Group's test plan, performed by an independent Bluetooth Qualification Board.
Because our device passed these tests, it will most likely work with other Bluetooth Qualified products. However, we cannot guarantee compatibility with every Bluetooth product on the market. Please come back to this page for updates.

Car kits make use of the Handsfree Bluetooth profile. This profile has core and extended functionalities. Car kits may offer extended functions not available on all phones. Car kits are a relatively new area of technology and are evolving quickly.
1 - Screen on smartphone does not wake up if call is made from car kit when Treo is in sleep mode.
2 - Incoming caller ID showing as "********" for known and unknown calls.
3 - After making a Bluetooth connection, you may hear a squeaking sound for about 5-7 seconds after you dial a call, before the first ring tone. This only happens on the first call; subsequent calls will not exhibit this issue. It will appear again if you disconnect from the Bluetooth car kit and re-connect.
