Is there much difference in the fitting process for each type? The BMW pdf shows it fitting in the dash, but I thought it replaced the unit on the trunk floor.
The Combox dash
install is when there is no
Telematics (TCU) unit in your car at all. The Combox trunk
install is when there is a TCU in the car: http://www.m3post.com/forums/showthread.php?t=560216
Will I need to run any cables up the car and does the armrest area need to be pulled apart?
You need to get the CAN wires to the Combox harness. I use the iDrive Quadralock CAN wires for that. I do not remove any armrest parts unless a Video port is to be installed and then I only replace the existing OEM USB port with an OEM USB/Video composite port.
