Ok. After Teyes finally got back to me to sort out the problems. The active parking lines are now working but only by connecting the obd connector up which has also given me the doors open symbol on the screen. Apparently I updated the apps on the unit and it updated the car info one with vesta, that is why the a/c controls weren't showing on the screen. As far as the mic is concerned they sent me an app to install which then gives you the option to turn the external.mic on, I previously didn't have this setting on the system, and now the external mic works fine. The setting is under Factory, and is at the very bottom. If you dont have this i have attached the apk they sent me. With this setting they say you don't have to disconnect the internal mic.
