I have an option to purchase a COMAND 2.5 out of a W220 s-class that has unfortunately been involved in a very serious car accident (all OK). The unit is out of the car, is australian-spec, according to the car owner does not have a tv-tuner, and comprises a metal fascia to which three DIN sized boxes attach to the rear and a screen and buttons in three parts to the front with some ribbon cable.<br> <br> I am considering this as I am building up a car at the moment to my own spec (non MB), at the moment the interior is bare metal and the w220 owner has suggested that this would be a nice touch for my car, having ridden in his s-class when it was alive, i can't agree more . But exactly what else does this thing do, we played cd's, i know it plays tape, and used satnav also....<br> <br> Has ANYONE completed this translplant with any degree of success ? if I can get it to work i'd like to retain as much functionality as possible. These guys http://www.megacomm.de/menu/menu_telematik_mb/menu.htm seem to think installing a COMAND 2.0 system would be easier, unfortunaly there isn't one for sale around here at the moment .<br> <br> The owner is willing to sell me the CD stacker also and i can see already it hooks up largely via the fibre optic out on the middle DIN box. <br> <br> having done some research on this now there is a data bus (CAN-bus) mb uses between interior devices (i believe there's a separate bus for engine signals), does the COMAND system act as a gateway ? how much of this bus neds to be emulated for the COMAND system to work ?<br> <br> also, we can't yet find the amplifier for this thing and are wondering if it's on-board of it signals are put out at line-level and an external amp can be connected. I've heard rumors the amp is digital...... does anyone know the specification of the amp ?<br> <br> any idea how much a used tv-tuner goes for ?<br> <br> any help appreciated.
