Default JB4 OLD POSITAP VERSION - 02-21-2019, 11:10 PM


I bought a BMW F30 335i PWG few years ago and I got it with him JB4, but this JB4 has been disconnected from car.

I want to connect this JB4 again but I have a few questions about my JB4 F-SERIES N55 PWG POSITAP version.

Do I need to upgrade firmware version, do you have this newer version of firmware for my version of jb4 and can I update my version of jb4 to obdII version?

I believe you can upgrade to the obd2 and run you can wires over to the obd2. There's even a way to positap to the back of the obd2 for a clean install.

You'll need to check with Terry.

You need the OBD and the side connector for retrofit before updating your JB4 firmware.
