hahaha are u serious? exact same thing happened to me. I gave them a CAN-01 and it was faulty so ended up using one of their units aswell. My AVIC just turns off when i turn the key off, im not really fussed there.
I hope they looked after you :) I was back there last thursday to have some rear speakers fitted. Should be back there in a couple of months again for the reversing camera - where did you get yours from (reversing camera)? oh, and how did you get your maps updated to R18?
