|Fm 750 monitor. |
Keep getting a message like no terrain compensation.
Un plugging / replugging wire to the box does nothing.
Unplugging / replugging cable to Sm 200 or restarting fm750 makes it work. In the past for quite some time. Now it might do it again in minutes or 1 minutes.
Connector on sm200 is slightly loose. Wiggling it don't seem to do anything. Bending the cable that plugs into the sam200 sometimes helps. Tied that cable to steering column helped a little.
Infrequently get a error code 12.
How do I figure out a solution?
