Hi all, sorry if I am asking questions/raising points that were already asked/discussed. I am the owner of an 2016 Superb without Canton/Apple Car Play/Android auto HU. About 3 weeks ago my satnav and Bluetooth stopped working, however the rest of the HU functions(radio/DAb radio, CD, aux) are all OK. My question is, is my Harman Audio unit faulty and how to tell for sure without going to a main dealer if this is the case? If I am buying another MIB 2 unit(used), would it be plug and play only if the supplier part number is identical with mine? Or any other MIB 2 units from VAG group cars would work as well? Any ideas, suggestions, advices are more than welcome! Thanks in advance, Adrian
