I currently have bose in my A4 (B6). The system is great, but I find there is no control for the bass. Adjusting the bass level makes no difference.
I have looked at the soft coding via vagcom and my factory soft code was 01201. To switch off the BOSE EQ, I have reprogrammed the coding to 01011.
Now I don't get the BOSE logo when the HU is switched on which I beleive is correct if the BOSE EQ is disabled.
Coding was done via http://www.ibiblio.org/tkan/audi/radios/symphony2.html
Have I used the correct soft coding?
Should I have used 01001 soft code?
