Jb4 535 can't change maps.

DaHeadlightGuy · 02-27-2016, 03:33 PM

Just installed jb4 F series on my 2012 535 but cannot change maps. Held the volume button down no flashing on the shifter. Got the harness type b everything is connected. Only 2 wires coming out of the box is power and ground.

Have tried it with the 4pin to obdii connector hooked up and disconnected. Still same results no flashing of the shifter.

Can someone lend me some insight. The jb box is a long plastic cased rectangle with harness coming out with 2 loose wires power and ground. No serial cable like I have seen in many other installs.
