coding + jb4 on

does jb4 have to be on map 0 to do coding?

or it should work on any map... would it cause communication errors?

It must be on 0. It won't work on any other mapping

I seem to get a lot of communication errors even on map 0. It used to work fine all the time when the JB4 wasn't installed. YMMV.

Garage List
Never had an issue related to JB4's as long as I turn them to map 0.

Other errors must be unrelated issues.

Map zero works.. Something could be wrong in your JB4 install
