Back to cb in my semi.

I prefer it on the dash, I'm out of Phoenix Arizona and never had my GPS, scanner or radio get damaged by the heat and it's usually 115 here in the summer.

There can be conditions where ambient temperature isn’t the only concern. I pretty well cooked a phone left inadvertently on the dash here in FTW. 30-minutes, maybe.

The GPS is old and reliable. But a bandanna is real cheap insurance. Parked for a ten I use custom-cut Clean & Cool interior shades. Worth every penny year-round

Use a laser temp device. Devices do heat up.

The second reason (hiding them) is enough to fab a cover. What you have is both unusual and is therefore notice-able. Sticks out.

In reference to police scanner laws and ham radio licencing, look at what you have. Does the receiver or it's packaging, anything marked as "police scanner"? I've never owned anything that did. My last receiver was capable of receiving analog frequencies but, most entities are digital so on the level of performance for the most part is, unless transmissions are simulcast to older infrastructure, I can't "scan the police". Mainly, that receiver was programmed for all services and then some, that I'm already licensed to operate. That's VHF/UHF Ham radio and GMRS. Then I added FRS/MURS, more VHF/UHF, railroad and maritime along with aircraft. So, I listened to pretty much anything OTHER than police, fire or medical, unless such comms either bled over or by happenstance on the aircraft's band. Unless you're running a digital radio set for any system in your area or not, I don't think any agency has a foot to stand on. I've had a couple of inspectors miss out on seeing extra radios
on my dash during inspection, especially passing the coop on either side, and most sure that they can see my dash on one or more cameras. Most DOT officers I spoke to could care less about my interest in the scanning hobby.

I got inspected once in Ohio, the officer asked what the radio was on the dash, I said it's my ham radio, she did her level one, then proceeded to say how she's studying for her ticket, and asked a bunch of questions about different bands and types of operating.. She stated she wanted to get all the way to Extra.. I assured her she could do it, and left her with an eyeball QSL card..

Got an email a couple months later with a picture of her, and her shiny new extra ticket. Said she went for the first test and came out a General, missed Extra by 3 questions, studied a bit more, and next test session, got her Extra.
