    I have a 2015 Tundra SR5. It has the HD radio that is XM capable. I recently got my hands on a factory radio with navigation. I installed it and everything appears to work fine with the exception of the volume adjustment. Nav works, bluetooth works, radio works, steering wheel channel controls work. Just cannot adjust the volume with the radio knob nor the steeering wheel control.

    Buddy of mine is a toyota mechanic. We haev pulled various fuses trying to "reset" the radio. Nothing works. He said there is a slight possibly the amp bieng different might casue a problem or the radio just may be broken.

    Anyone have any suggestions?

    The amp being different is possible.
    OEM amps typically handle volume two ways.

    The first way is like any regular aftermarket head unit does. More or less turn the knob up and it increases the voltage to the amp. The amp then amplifys that signal.

    The second way is... well... I don't really know. The head units dosent send a line voltage, though. The typical aftermarket amplifier unfortunately do not work with these types of head units without having a device that can add in the needed voltage.

    Then again, maybe the mute is on.

    I wonder if it's broken, since all the other controls work.

    Doesn't matter if you get volume knob working. That radio is shit. Won't get loud enough to listen to with the windows down. Even with factory amp under passenger seat.

    Sold mine out of my 2019 CM on eBay.

    Get aftermarket. They make plug and play.

    Pure crap.
