Nissan Roox MOST bus fault

Guys, I'm tearing my hair out! My 2010 Nissan Roox with a gasoline engine is driving me nuts. The audio is completely dead, the navigation is kaput, and the error memory is screaming about something. I think it's a MOST bus fault? Anyone seen this before?

A 2010 Nissan Roox is experiencing issues with its audio and navigation systems, suspected to be caused by a MOST bus fault. This fault indicates a break in the communication loop between the car's control units. While checking fuses is a simple first step, resolving a MOST bus issue typically requires professional diagnostics to identify the faulty control unit. It is advised to have the vehicle scanned by a knowledgeable shop to accurately pinpoint and address the problem.

Whoa, that sucks! A MOST bus fault, huh? Yeah, those can be tricky. Basically, it means there's likely a break in the communication loop between the control units in your car. Have you tried checking any fuses related to the audio or navigation system? Sometimes it's something simple like that, but MOST bus issues usually mean a deeper dive.

Thanks for the reply! Fuses are all good, I checked them first. By deeper dive, do you mean I should start unplugging things to see if it resets? I'm kinda handy, but I don't wanna fry anything!

No, no! Definitely don't start randomly unplugging things. You could cause even more problems! A MOST bus issue usually points to a faulty control unit along the bus. If you're getting specific error codes related to the MOST bus, it's probably time to get it scanned by a shop that knows their stuff. They'll be able to pinpoint which unit is causing the problem. Sadly, it can be expensive...be prepared to shell out around 1000€ depending on which unit is busted.

Thanks a bunch for the info! Sounds like this is beyond my skill level. I'll bite the bullet and take it to a shop. At least I know what to tell them now! I owe you one.
