This looks to be a nice product (Motorola T505), that is getting good reviews from tech sites:

A few things that stood out to me, rechargeable, clips to visor, voice caller id, and the station finder function.

It retails for $139 USD on the Motorola Shop site, but can be found on ebay for around $100 USD.

Looks pretty interesting...the only downside for me would be that I'd have to keep changing the station, as I tend to listen to the radio much more than stream music in the car.

I presume I could switch between my listening station and the T505 "talking" station via a preset, which would be relatively easy.

I've been looking for something that would give me voice over the stereo w/out a wired install. I may give this a try.

This is a good point. Never thought about those people that want to listen to the radio normally. If you try the T505 out, please post a review to the forums.
