There are several reasons with the big one being that the Wouxun makes my Jeep cluttered. I like that the Midland is all in the mic. The quality feel of the 575 is another, and then the simplicity. So when I'm not using it, it disappears, or at worst, hangs on a mic holder out of the way and without looking like clutter. It also has better volume so I can hear it with the top down. I had to use an auxillary speaker with the Wouxun, even with the mic speaker and the base speaker turned on. The mic speaker is so weak it might as well not even be there. The Wouxun's backlighting is terrible, too. Too bright at night. You can't dim it or change the color. And the best location of the face plate, which worked well for info and usage put that light in a bad spot for me at night. (Top center of the dash.)
The Wouxun has performed well in terms of range and reception, but the 575 is just as good there. But again, the higher volume makes it superior.
So I liked the Wouxun from a performance standpoint, but ergonomically, it just doesn't work for me.
It is going on Ebay or FB Marketplace soon if I get no reasonable offers here. I have the box and all the cords. There isn't a scratch or mark on it, so it is in new condition. $320 takes it, shipping included within the continental US. If local, then $300.
