Great little radio

I bought the uniden 520xl for my Nissan due to limited mounting space. The size and features of the radio was making it a perfect radio for my hunt club. Unfortunately, I returned it, but only because I was offered another radio for my truck. The customer service was great. I am new to the CB scene and they helped with any and all questions I had. Will be back for radio equipment for my other vehicle.

Good radio for off-roading

This is a good radio that I have used for several years in my off-roading rigs. I now have one in each of my 3 vehicles.

Uniden Pro

I purchased the Uniden Pro 52o XL to replace my three year old Midland. The Uniden performed well on my 940 mile Subaru charity drive. I only have good things to say about my purchase. Thank you for a great product.
