Looking for manuals and 12 pin accessory pinout info for the
Uniden SMU4525KT / Standard GX1510U.

I'm hoping someone's got the manual in pdf or scanned into jpgs.

Still looking for pinout info.

Yeah,
Me too.
I'll keep up the search for the docs and if I get lucky I'll either let you know where or send you a copy of what I get.

Appreciate the same if possible.

The accessory connectors on Uniden LMR radios never came fully loaded. They alwasy left them open for dealers choice. In the case of SMU4525KT there are only 3 pins wired from the factory. Pin 1 is Ground. Pin 2 is the main audio line from the audio amplifier. Pin 3 goes to internal speaker. The radio would come from the factory with a white jumper wire connecting pins 2 and 3 together to activate internal speaker. If you want external speaker you cut the jumper and connect the speaker across pins 1 and 2. All the other pins are open. If you would like a schematic let me know.
