A few months ago I picked up a Cobra 25 to replace my Cobra 19 for two reasons, better RF noise filtering and to have a more effective radio when asking for information. It satisfied both needs, but this is the only place I could realistically mount it...
It was easy to control there and kept the mic out of the way, but I had to be diligent about putting up the windshield sun shade once summer came or it would be too hot to touch after a few minutes. It also felt like I was always leaving a $100 bill on the dashboard, and the aesthetics are obviously... poor.
In search of a stealthier installation I picked up a Uniden 510 because I remember seeing it at a truck stop and being impressed at how thin it was. My plan was to simply stuff it between the driver's seat and the center console. It fit there, but it pushed up on the side bolster which I could feel in my ass. I considered mounting it under the steering wheel, but that would have the problems of getting in my way when I enter and exit the car and I would have to reach forward and under the wheel to control it.
After holding it in different places, I figured the best place for it would be attached to the center console under my right leg. I didn't want to drill any more holes in expensive trim pieces, so I came up with a bracket that uses the stock screws that hold the console in place.
Please pardon my craftsmanship. I'm not very skilled, but I usually get the job done.
I'm not much of a photographer either. This is where it attaches to the front screw.
...and the rear. This is usually hidden by the seat.
View from the driver's seat, also showing Uniden ESP-5 external speaker. IMO, an external speaker is essential with these little radios because with the internal speakers I can barely understand conversations that aren't coming in strong.
I'm pretty happy with it. It seems to have a much more effective automatic noise limiter than the Cobra 19, which cuts down greatly on the ignition noise and makes it easier to set the squelch. I don't really talk on the radio much, so I don't know how it does there, but I did get a Workman DM-452 power/echo microphone to replace the dinky little POS it comes with. I know it won't get out as far as my peaked and tuned Cobra 25 with an upgraded final, but I realized that I don't talk on the radio enough to really need it. I'll keep the Cobra for if I get another vehicle that has a reasonable place to mount it.
