No Power on MB Quart
Stereo switch will light up, but no power on the MB Quart. Checked fuse and looked fine. Any ideas?

If you have a a wired remote on the transom try disconnecting it. When they get wet they foul up the headunit.

Elaborate on " no power on the MB Quart" if you can. Do you mean the turn-on rocker lights up but the head-unit does not, or do you mean you are using a volt meter at the back of the head-unit and do not have B+ where you think you should?
The helm mounted rocker supplies voltage to the head-unit's red turn-on wire, but does not actually power the head-unit. This is done via constant B+ and GND on the head-units yellow MEM and black GND wires. All 3 are needed for the head-unit to power up.

Basically I flip the rocker switch to turn the stereo on. The LED for the rocker switch is on, but the MB Quart doesn't turn on. No lights, no music, no response?

You check the breaker under the stereo area?

They obviously bumped something loose if it worked before they changed the USB cord., could be power, remote or ground that came loose.
