Toyota Yaris Audio with dockable Tom Tom

[Droid13]

My dealership is offering these Yaris audio/bluetooth/mp3/usb with TomTom nav OEM systems as an upgrade for my plain am/fm/cd system in my 2004 sienna at a reasonable installed price.

Just wondering if anybody has any experience/comments with these? For the most part, I am ok with the audio quality of my existing Sienna'a audio system (just don't want to go down), I just want the additional features such as MP3, USB, bluetooth, and nav features this would add while maintaining the original sound quality...

I just picked up a portable Garmin GPS and started using it. I wanted to keep the dash stock and also move the GPS from car-to-car and rental cars. I also got a fully featured one (Nuvi 780) for under $200.

I find it is easy to mess with the control options and take your eyes off of the road. It is better with the GPS up on the top of the dash so you can see both the GPS and road at the same time. Just my 2 cents. Portables have the hardware and cords to put away at the end of the trip, which in-dash units avoid.

If the in-dash unit has the feature set you want, it seems to make sense for anti-theft protection.
