Harman Kardon SA688 Retrofit on F30

LuchoF30 · 03-06-2022, 08:52 AM

Hello, I tried to retrofit the Harman Kardon amp on my 2013 F30. When i VO coded 688 the logic 7 menu appeared, but it showed a warning "no warning sounds". When i connected the amp with the optic cable the warning disappeared and i can change the eq settings in the menu, but no sound whatsoever, i can't play radio, nor my music from music collection. It's stuck like its on pause. Also when I added 688 to VO and coded hu_nbt no amp ecu was found. Do you have any ideas? Much appreciated.

It sounds like you have a break in the most bus somewhere if you're seeing the no warning tones message on the HU.

When you code HU_NBT with 688, that should enable the most emitter on the HU so I'd check and see the most ring is complete between the 6WA instrument cluster, NBT and 6WA cluster.
