I managed to get 1/0 gauge cable through the main grommet on the drives side but i wouldn't suggest to do that - WHAT A PAIN IN THE ASS :D had to cut it and silicon it up! Other than that like others have suggested i got my coax though the passenger side of the firewall pretty easily!
Hey guys, Ive got a car PC laying around here from when i had a Subaru and thought id put it to good use in the Navara. Now when i originally had it setup i was running the best screen i could find which was a Lilliput.
Its very hard to find just a straight double din touch screen monitor...
