Excellent product
I have owned many Motorola wireless products before with mixed reviews.
This speakerphone works as promised, constructed well, reliable and easy to use.
By far is is the best Motorola product I have bought to date

Much Better Than Expected
I was just about to spend 0 on installation of a Mazda kit that would allow me to play Mp3s in my car. I knew this item played music, but I didn't realize it was through the car's speaker system. Saved me a bunch of money! So this is what happened.

Unaware of the music playing functionality, The MOTOROKR appealed to me because I don't like blue tooth headsets that hang on my ear. Talking from a device on my visor sounded intriguing. Got it for this reason alone, and the sound quality was surprisingly good. Then to my surprise, I discovered how well it plays the MP3s on my iPhone! Not only does the speaker sound decent, but the FM Transmitter functionality allowed me to both play the songs, and phone calls through my car's speaker system. Of course if I'd read the box in detail maybe I'd be less surprised, but either way, I think this technology is really cool. For someone who has a phone that plays music but no auxiliary out to plug the device to the car, I recommend this product. While I can't use my car's built in steering navigation to switch songs, I can easily change songs using the device while barely taking my eyes off the road.

Also note that I previously purchased an FM transmitter to listen to my phone in the car and the sound quality was horrendous. For some reason the FM transmitter functionality in the MOTOROKR T505 works just fine in my car. To be fair it could be because my first try I was in a big city, and with this gadget, I'm in the suburbs, but I'm not sure.

Great product
I bought this for my husband(he's the Tekkie in the family)and he loves it. I am ordering one for my car today!

Excellent Product
After using the T505 for a month I highly recommend it. It was extremely easy to set up and it easily recognized my Blackberry 8330. No longer do I have to drive with the "thing" in my ear. The loudest volume on the T505 allows me to easily converse on my phone even while driving on noisy highways. The speakerphone is very easy to power on and off, and it is very easy to answer incoming calls. The T505 easily attaches to the visor and is very securely attached. Also, being able to charge the speakerphone with car adapter ensures I'll never be without a hands-free device. I've not used the speakerphone for transmitting music through my car's audio system as I have no need for that function.

This is a product that performs as advertised and I heartily recommend it.

Ok for now
I had to return product and have it exchanged for a new one. I got the replacement and it is now working fine.....I like it.
