Lent our son our truck - he connected to bluetooth- now it is greyed out and can't do anything. Tried removing it from the phone- now we can't find it at all. Tried disconnecting battery, removing fuse, turning the key and holding the setup button while turning lights on/off 3x's and holding init button and selecting yes. Looked for a software update/nothing. Toyota is going to charge us $125 just to look at it. I would like to just fix it myself if I can.
