## Questions & Answers

**Q: Hello! Can this radar operate wirelessly (by batteries) without car cigarette lighter adapter? I have Tesla Model Y so don't have a cigarette adapter.**
A: No. Also, you have a cigarette lighter in the middle console. I have a model 3. Bought a phone mount and stuck it to the back of the screen, and got a long flat cord for the radar detector and tucked it in to the middle console trim and run to the plug on the inside.

**Q: Are these 'brand new' units ? uniden says they will honor warranty as long as the unit is purchased brand new.**
A: The one one that i received was brand new.

**Q: Folks that got new units, who was the seller?**
A: It’s normal

**Q: Looking for stealth technology. Is there anything out there that will disguise my car as an ostrich when going faster than speed limit?**
A: No. There are laser only that scramble the signal.  Very expensive and only justified if you have a lot of laser guns in your area
