Whats the best way to detect if the mic has got any issues? Tried following -> Disconn the -ve terminal. -> checked with Accumen Motors, Pandit Akurdi.. Both did not have the scanner and was sent to italy it seems for quitea few weeks. It strange that the ASS have to get software upgrades by shipping to italy.. -> Tried checking the cabin light but couldnt make much from it? Any thoughts? btw, i have not done any upgrades I believe the software version is still the same that i purchased in Sep 09.
