2013 Toyota Camry - Bluetooth issues

bluetooth keeps turning off and on. how do i fix problem

First, try pairing a different phone. If it works reliably there may simply be an incompatibility between phone and car. If the problem persists, it’s probably a bad Bluetooth transponder. Yours might be in the dash, the center console, built into the radio head unit, or somewhere else completely. A car audio shop will know.
