I just installed this exact same unit yesterday. It is really nice, and its small size makes it really easy to install. I haven't had a chance to test out transmitting, but it seemed to have good reception.
BTW I found one here in Portland, Oregon (at a Fred Meyers) that was in their closeout electronics for $40!
I Like my new Cobra 20XTR w/Neon Blue Illumination. Good Features, its small size and looks pretty cool at night. It can be powered by a cig lighter outlet for portability or hard-wired. The one i wanted though is the Cobra 148 NW ST Mobile CB. Its got 40 AM, 40 Upper Side Band and 40 Lower Side Band Channels and a boat load of other stuff.
