brunter......I found the coax easily enough, but couldn't find the power supply. On my coach (don't know about the newer ones) there is a panel on the dash above the instrument cluster. I removed the panel and finally found the wires there.
I had an old Cobra CB that I was going to mount in ours, but just couldn't find a spot that looked good and was accesible. I gave up and bought the the Cobra with everything built into the microphone. The radio unit mounts under the dash and out of the way. This radio performs well and has a "Scan" feature that the larger radios usually don't have. It also has a weather channel.
