Hi guys,

Any idea why my rear sound (bass&medium) + subwoofer don’t work anymore? Do I need to update the MHI2?

If you have Canton it’s more likely going to be the amp under the passenger seat.

Not sure on the latest MIB2 version but if you don’t have it it’ll be worth getting I would say. There’s a pinned thread at the top of the Audio and Electric forum

I’m talking rubbish - that’s map updates.

Have a search in this forum; there’ll be the right version floating around!
