I have the same unit. Have had it for 3-4 months now. Its not bad. I got it REALLLLLLY (like really really really) cheap, otherwise i dont think its worth the money. Its a nice thing to have, but the price is crazy. BTW, the 910 has been discontinued, and now the 911 is available. Its no different in any way, except the front panel color, and supposedly controls a sirius tuner. I dont see how, since there is no extra plugs anywhere, either in the headunit or the brain. I actually have a 911 inside a 910 case, and use a 910 brain. Dont ask me why
but i cannot see any difference whatsoever.
