OK, so this isn't an EVO specific accessory...but holy hell, the Motorola T505 is one bad ass mamma-jamma. Essentially, it uses Bluetooth and an FM transmitter to play tunes from your EVO through your car. In a major metropolitan area this thing worked great...streaming Pandora was awesome. You can also take calls with it. For ~$60 after shipping, this is awesome. No wires needed - just pair and go. Use in any car. Use with any Bluetooth device (other phones, etc...) Stream all your music in your car. The down side is that it'll drain your EVO battery (get a car charger, you putz) and that it's not hard-wired into the car stereo...well, no shit. But it's also quicker, cheaper, and easier. The sound quality was awesome. MOTOROKR T505 - Motorola I see this has been around a while, but my brother told me about it and I ordered it last week. If you're looking for a way to play Pandora/MP3s from your EVO in your car (any car!), then this is it. Now all I need is my dock and I can run Google Navigation whilst streaming Pandora and I'll be in heaven.
