Afternoon guys,
My recently acquired R230 has an apparently dead Comand head unit.
The red battery warning was on the dash when I collected the car but was listed as a stored fault, so I used my iCarsoft and cancelled the error, which then disappeared.
It came back on for around 10 seconds a few days later but vanished again.
I have a voltage meter plugged in and battery is charging at 14.1 when running so no alternator issues.
Disconnected both batteries for around 2 hours last week in an attempt to reset the head unit but still won’t fire up.
Have got a new Kenwood head unit to go in but don’t have the correct cables to connect as I have just discovered the car has an amp fitted, along with the DVD nav unit and cd stacker.
Does anyone know the cable connector I need but also if there are any other possible reset procedures for the Comand unit to see if it dead or just resting?
The other issue I have regarding checking fuses on the Comand is mine seem to have a lot less fuses and fuse sockets than is shown on the available maps, so not even sure if it might just be a fuse?
Sorry for the essay, maybe pics will help?
As you can see on the fuse photo, fuse 77 does not exist, so is it all powered through the amp?
TIA
