Personally, I'd spend the extra few dollars and get the digital unit. It has auto volume so there's no need for a the boom boom that Rendog is talking about around town. If you don't wan't any music for a few seconds, just say something and the music mutes.
It's pretty much "set and forget" so you don't have to worry about being a genius to work it all out later.
I picked up my power straight from the battery as the unit will only "power up" if you have your helmet plugged in.
I'm running an iPhone from which i use it as a phone, (Duh!) A GPS, and an MP3 player, all in the one unit.
I have a seperate waterproof FM radio.
I also have a seperate GPS that I only use for FarRide and IBA rides for distance and average speeds.
I'm currently looking for a GME TX3100 UHF to slip into the fairing pocket to connect up to it as well.
And yes, I'm very very happy with my Starcom1 Digital!

You'll find Dale from DMME is very helpfull. He helped my rig mine up over the phone and I didn't even buy it from him!
If you need any more cables, headsets or even spares, he sends everything express post if you need it in a hurry or not.
