However, my one complaint is that the controls are somewhat difficult to adjust, particularly volume and squelch.

The Bad...audio quality and volume are really bad.

The volume is much better than I expected it to be, and the controls are arranged on the mic in a way that is easy to use

Only issue is volume and the screen could be better IMO

I have not as of yet had the top down since installing and cannot speak to the volume levels while in an open air drive but with the top up, the volume is perfectly loud enough for me to be able to hear the conversation loud and clear

Speaker has already lost some volume
