Tipo MOST Bus Fault

Woah, that sounds eerily familiar! I have a Tipo as well, though I can't remember the exact year. I had a similar issue a while back. Complete audio failure, navigation dead, and that dreaded MOST bus error. Did you check all the fuses related to the infotainment system? Also, are you getting any other weird electrical glitches?

Thanks for the reply! I did check the fuses, all seem fine, sadly. No other electrical issues that I've noticed, everything else seems to be working perfectly. Was your issue exactly the same, just the audio and navigation gone? Did you manage to fix it yourself, or did you end up taking it to a shop?

Yep, exactly the same symptoms. Just the audio and navigation were affected. Honestly, I tried fiddling around with it myself for a bit, checking connections and all that, but I quickly realized I was out of my depth. Ended up taking it to a specialist. They confirmed it was a faulty control unit on the MOST bus. Saved myself a lot of headache by just letting them handle it. Probably best to get it checked by someone who knows these automotive protocol systems inside and out!

Thanks a lot for sharing your experience! Sounds like I'm heading down the same road. I'll book it in at the workshop then and get them to take a look. At least now I have an idea of what to expect! It's good to know that somebody else had the same problem and that it's fixable.
