Hi, I've been trying to help a friend with an A6, fitted with the MMI Basic Plus unit with Navigation (I believe). He's asked to unlock the Navigation disc drive to swap to a European Map disc while on holiday. After trawling through the control modules with VCDS, all I've been able to find is in Navigation 37 - Adaptation Channel 64 will eject the disc once, but I'm trying to enable the disc drive to eject using the button. I know this can be carried out using Adaptation channel 68 on a 2G MMI high unit, but does anyone know what needs to be coded for this unit? Pictures of the set up in question. Any ideas anyone?!
