Hands Free and MP3 Ideal Setup

Treo 650 Forum Post

I have a Treo 650 and a Lexus IS350 (IS350 does not have Navigation). I wanted to get thoughts on the ideal setup for the following:

My car has an auxiliary input for plugging in ipods and the like. I want to be able to

1) Run a cable from my treo (headphone jack) to the aux input. I have the 2.5mm to 3.5 mm converter.

2) Answer phone calls as easily as possible hands free. Preferably through a bluetooth connection like one of the following:

a) Blueant Supertooth II Speakerphone for Treo 650
b) Vox MV900 Bluetooth Speakerphone for Treo 650
c) Mr Handsfree Blue Vision Speakerphone for Treo 650
d) Motorola T305 for Treo 650

3) Make commonly used phone calls through some voice recognition software.

4) Possibly use my treo as a Car navigation system.
I had done this before using Tom Tom Navigator 5 and the Seidio Hands free system. I did not like the Seidio system I had before ( a couple of years old) due to all the wires and no convenient way for me to attach to the car. Also, I found that the Tom Tom 5 tended to hang more frequently than I would like.

Accomplishing 1 through 3 is most important to me. Accomplishing #4 would be nice. Are there going to be issue with a Blue Tooth GPS unit and a Blue Tooth Hands Free phone speaker system.

What are your recommendations?

I have a SVT Focus with bluetooth in it anda 3.5"sterio input jack.

I listen to MP3's through the jack with the Treo, When the phone part rings (while conncected bluetooth) I just hit the phone answer button on my car steering wheel.

I have no idea about voice recongnition, that lexus was like 40 grand and it doesnt have Bluetooth built in? My 18k focus does though LOL go figure.
