MB Quart PSAP-3S Universal Dash mounted plug w/ USB, USB-C and 3.5mm fits GMR-7

The PSAP-3S moves your source unit rear USB and auxiliary inputs to the dash, where you can actually reach them. Most receivers bury those connections behind the chassis, which means unplugging a phone turns into pulling the radio. This adapter runs cables from those rear ports to a panel-mounted plate with three connections: USB-A, USB-C, and a 3.5mm audio mini jack. Included cables cover each path, with a 3.5mm mini-jack to RCA cable, a USB-C to USB-A cable, and a USB-A to USB-A cable. Audio playback through the jack is supported, and the USB ports handle charging and media. Installation uses a standard Carling style switch knockout at 0.8 inches wide by 1.3 inches high, so most side-by-side, boat, and RV dashes already have a spot for it. The unit measures 1.9 inches high, 2.4 inches deep, and 1.0 inch wide. A built-in rubber seal and front cover keep water, dust, and debris out of the connections when nothing is plugged in, which is the difference between this and an open panel port. Fitment is universal across MB Quart and other source units, including the GMR-7. The finish is black.
