I have a Kenwood 710A mounted in the back of the vehicle near the 3rd seat. I need to pull comm cable (DB9) to the vehicle dashboard area in order to get to the AVMap G5 gps. I am putting in a tiny trak4. Has anyone had experience pulling cable above the roof liner while staying away from the side airbag curtains? I have no room left on either side of the floorboard....Any suggestions?
