Hi everyone, I just bought my first Prius ( model 4, 2012). I have the HDD navigation system. I was told at the dealer the CD player " holds 6 CD's, 2 slots are used up for the DVD's for the navigation system" I can only load one music CD. Does anyone know if this CD player is a 3 CD player? Also, how would I access the two DVD'd that are used for the navigation system? I called Toyota and they did not know and I cannot find the info on how to get to the two navigation DVD's. thank you
