    • Remove brown copper tape with the FPC (not clipped). Removing of the copper tape is necessary, I didn't find a way to avoid it. Try to remove the copper tape as gentle as possible to reuse it.

    • Also remove green tape with angled tweezers and unclip in a 2nd step the FPC from the board

Hi, i have an issue with Garmin Edsge 830; the problem is that the device cant connect to the phone and the official statemenet from Garmin was that the bluetooth sensor is not working. Is there a way to reapir it? i guess it is soldered on the motherboard, meaning i should change the whole motherboard?

Thanks for the answer
