I used this product with my Droid2 and immediately found that the Droid had to have it’s bluetooth cycled off and on each time I got in the car to be able to play music through the stereo.

The FM transmitter is useless. It generates a lot of picket fencing, even when placed within a foot of the car’s antenna. On battery power the signal fades within a few minutes to be like trying to pick up a FM station 100 miles away with lots of static and the stereo locking and unlocking constantly. It does much better when the power cord is plugged in or you have a finger touching the unit (using them for antennas, I suspect) but neither of these solutions are feasible or practical.

Any music played sounds awful. The unit imparts a huge tremolo to any music played that will give you a headache within 5 minutes. It makes a expensive sound system sound like a $5 chinese boom box from Dollar General.

To make matters worse, the internal speaker isn’t loud enough to overcome normal road noise which makes the entire unit a $100 waste of money.

I tried the unit in 4 different vehicles (Mazda3, Mustang GT, Geo Prism, and Chevy Suburban) with no difference in behavior. I also tried it through my Bose wave radio in the house to verify the FM reception (or lack thereof).

It’s hard to believe that Motorola would release a product like this. I would certainly expect better of them.
