Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

1 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

View attachment 115201 My PCM 3.0 recently had an issue on the map. After you press the map button, the PCM map screen go all black. You can still control the zoom in zoom out with the right knob but the screen still blacked out. Took it to the dealer, they say is the PCM issue, replaced me the whole PCM with a rebuilt unit. Same problem occurred after, they say is the antenna issue, replaced the antenna. Same problem occurred after, they say is the wiring harness issue going to the antenna, replaced the wiring harness. Guess what, after couple weeks, same thing happened again. I asked them couple times will it be the map version problem that had a glitch leading to the blacked out screen, they said no and refused to update me a new map. Anyone has idea what's going on?
