Does anyone know how or why the satnav won't spit the disc out when I press the eject button (I hate electrical things) I suppose at worst I could always use a hammer on it but it's now the second (expensive) radio, cd, satnav head I've installed since new. Everything about it works OK, the CD, radio and including the satnav but it just doesn't eject the disc . Even the 6 pack CD autochanger still works OK which must be a first.
