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.

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

0 evidence records excluded for query context · 2 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

I'm thinking of replacing my PCM with a headunit, specifically one that supports CarPlay . I like the reviews for the wireless Alpine CarPlay unit, perhaps I will go with that. I will use my existing Bose amp . But what happens to the car related features in the PCM when it's removed? Things like DRL's, interior light settings, rear wiper settings, stuff like that?

POST 2Original post

I replaced my Bose head unit with a Pioneer AVH -2330 NEX which has Apple CarPlay and love it for the most part. Only thing so far I don’t like is your head screen will just mirror your iPhone screen so if you are in maps, but want to go to emails on your phone, your screen changes on the Pioneer screen. As to the PCM functions, the only thing I have observed is you can no longer see the various things displayed in your speedo screen. Most are still there like TPMS, distance, mpg, etc., but no nav system interface. Remember, with the Bose amp , you will have to use a MOST HUR unit.

POST 3Original post

Thanks Rosa. Isn't mirroring something you can turn on and off? Or do you want it on so that you can see your maps? It makes sense that there is no Nav info on the speedo screen. What does it say? Just the normal "Route guidance not active" message? I'm asking about the settings that you can find in the PCM when you press Main, then Set, then choose individual memory. You can turn DRL's on or off there, you can set your preferences for when/how the doors lock and the interior light settings, etc. Are they just gone and do they stay at whatever setting they were on when the PCM was removed?

POST 4Original post

I just got my PCM replaced. I found out that you lose the car related functions in the PCM .
