Ok, a friend of mine has 2 of these HU's, i was like stolen, gotta be!! Turns out thst one came out of a Mercedes that was totaled, and the brian was totaled as well. The other was purchased from local pawn shop, stupid pawn shop tried to hook the Hu up, and fried the brian!! No my question to you guys is this, can you get brains for these units, and I have been told that you need the orginal brian that came with the unit. I know these are some **** HU's , but what are my options with the info i have told you... Please help!!!
