What do you think is needed to have my BMW Professional HU accept the hifi recoding and stop the "cannot detect hifi harness" code?
@ Sir Technic
If I cant have this recoded to hifi I may very well do the MS-8 upgrade to get decent SQ but can I order a harness that would fit the OEM harness from HU? At least this way I will not have to cut wires from the OEM harness down to MS-8. Kindly throw me a pm of price and shipped to CA, USA.
