Just installed it like 10 minutes ago. Its a super easy job, even easier if you have small hands (which I don't). The sound is great, awesome control scheme. I have paired my iPhone with the car via BT, and I can still make/receive calls with the iPhone playing (it just pause the music). The only thing better than the GW100 is the GW300, which add a USB port for other players or USB drives. If you're still on the fence about it, go for it, and make sure you get it from Enfig.
