Hand Free and MP3 ideal setup?

[BadBrad]

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 will also post this to the blue tooth section.

There are gps car kits out there that also allow you to do everything else on your list. I havn't used very many, but let me dig some stuff up here...

Of course similar car kits/docks exist without the gps.

Hope that helps, and good luck!

Just a small caution....You might run into problems if you use the headphone jack in that manner. It is a very weak part of the 650 and the frequent use you describe could cause the jack to fail prematurely. Search these boards for threads about the headphone jack before you jump in just so you know what can result.

There is a Seido adapter that might help to save the jack. Take a look:

I am not trying to be a wet blanket, just want you to be aware. I believe the fact they have that product will let you know there is a problem. I am not sure if you need the connector on the phone for any of the other items on your wish list so I hope the adapter won't get in your way.

Best of luck,
