I have tried many transmitters but this tops them all. I have a 30 gig Creative Zen Vision MP3 player. This is the only unit that I have found that will allow me to hold my player, charge it and transmit my music to my speakers. I listen to it every day on my travels to and from work and on my travels. This is very universal with having a USB charger so you can charge even your cell phones! For those travelers that like their music and drive safe this is a must have item.

I bought this "Advanced Car Mount and FM Transmitter for Creative Zen" product for my wife and found it very good: sturdy construction, very easy to connect to car radio, good sound. For my G1 Android phone I currently use Motorola MOTOROKR T505 bluetooth/fm transmitter, which produces significantly more noise (that's probably because Motorola uses Bluetooth, while this FM transmitter connects directly to your device through 3.5 earphone connector). So, I'm thinking about buying earphone USB to 3.5 mm adapter to be able to use Advanced Car Mount and FM Transmitter with my phone instead of Motorola device.

The only thing which I'd like to improve is a player/phone grip. It needs better, probably softer and thicker pads for better grip. No, it's already pretty good, but it may easily be improved. I'd recommend its manufacturer to take a look at iGrip Universal Fit Flexible Mount at [...]. It grips much better.

2 times returning this because signal will not go through (?) with my sony s545. Not sure what deal is. Anyone else had this problem??
