Thanks everyone for the educating dialogue. Based on crippledpetey's excellent info I'm going to do a little more research into alternative setups. Specifically disconnect options and different CB install locations if I go with a different make or model. I don't want to lose my space in the arm consoles nor do I have a cage to install one overhead.
Correct me if I'm wrong but a Cobra 29 is more of a permanent install? That's the other one I've seen in other posts a lot.
I really like the size of that model. Seems like you can put it lots of different places (that's what she said). Is there any specific reason why you would recommend the 520xl over the cobra 75?
