Recently bought an enhanced Bluetooth coding file followed the steps exact until you have restart idrive so It can actualy overwrite the standard Bluetooth. looked on YouTube and hundreds of posts on here and still nothing that’s worked. Tried holding volume button/volume and mode/volume and eject, none of these do anything at all no matter how long I hold. Until I get this simple step done I can’t listen to music or know if it’s even going to work. any suggestions and what negatives would disconnecting the battery do if any ?
