Hey everyone, I'm looking to pick up a car charger / FM transmitter setup for using my Droid in the car and playing music through the car speakers. I found two seemingly similar products on Amazon:

Amazon.com: Accessory Power FlexSmart Car Mount System for SmartPhones - Cutting Edge FM Transmitter and Charger with DC Surge Protection and Stabilized Flex-Neck: Electronics

and

Amazon.com: Accessory Power FlexSmart Car Mount System for MOTOROLA DROID SmartPhones - Cutting Edge FM Transmitter and Charger with DC Surge Protection and Stabilized Flex-Neck: Electronics

They look the same to me (just one is $10 cheaper!) so I thought I'd ask if anyone had any experience with this device. How does it charge the phone? Is there a micro USB connector inside the dock, or do you have to use your own cord? Any other perspectives you can offer on these devices, or any other devices that would charge and do FM transmitting at the same time will be greatly appreciated.
