Cross posting this here (along with the F30 forum) since most F80/82 M's came with HK….
After doing a bit of research to upgrade the audio in my Harmon Kardon equipped F80 M3 (specifically the amp), I came across multiple threads that discuss the Bavsound Revenant (the old one, not the current Pro version), Bimmer-Tech (the rebranded Audiotec PP 86DSP) and the Match UP 7BMW/UP 7DSP (also by Audiotec). But these PnP amp solutions only work with HiFi equipped cars, not HK - presumably because HK cars have more speaker channels than these amps can support (assuming you want to use all factory HK speaker channels, which I would want to do).
Then I came across these three items from Audiotec:
Match UP 10DSP Amp:

Helix SDMI25 (MOST interface module):

BMW PnP Harness for HK Cars (F-Series):

It appears the Match UP 10DSP was released earlier this year so maybe it is still a bit too "new" which may be why I have been unable to find much info on BMW applications. Also, Audiotec does appear to advertise this equipment as a PnP option for HK equipped vehicles. But other than the literature on the Audiotec site, I have been unable to find any real world install/feedback on this equipment for HK equipped F-series BMWs (the F3x/F8x in particular).
I know the Revenant Pro by Bavsound is an option for HK equipped cars. But given an option, I like the DIY PC tunability of the Audiotec equipment, either by me or a local audio installer, over the SD card format of the Bavsound solution - especially since the price point is really close for both.
So does anyone have any insight/experience on this "new" Audiotec PnP equipment setup for HK equipped F3x/F8x BMWs?
