I just moved my R3 to my wife's truck and picked up an R7 for me. It is cold outside and I brought the R7 inside and powered it up with a 12 volt converter that plugs into the wall similar to the one pictured below. I wanted to get familiar with the settings and get it set up like I had the R3. Anyway, when I would come out of the menu settings, the display would flash off for a second or two and then come back on for a bit and then flash off again, and repeat. I suspect that it is because I did not have a lock on gps signals but could not find any documentation on it. After putting it back in the truck everything returned to normal. Are my suspicions regarding the lack of gps signal correct?

What about that power supply? If you try again, set the display to show volts received.

Most likely the adapter is not powerful enough and you are starving the R7. The R7 consumes more power than the R3 and these cheap adapters all usually have power rated in the miliamps... If you have a power supply that supplies over 2A or more I would bet its fine. Did you test in your car?

did you check to make sure the power plug is fully seated in the power receptacle? Some people found Uniden's new power cord didn't fit so well.

Its the 12V source. Ditch the converter and try again. Don't keep using that converter or you may damage the R7

Try a Escort non coiled power cord, it allowed enough power to get through. You adapter there unless it is not working to spec should be enough. I have seen this myself using R7 and M1 dash cam together on Uniden power cord. Does the same thing related to being starved for Power. Escort cord, works fine. It is not the pin outs. It is the cord. Oh, make sure you are using the R7 cord not the R3 cord. The R3 coiled chord is even thinner and more flimsy (IMO) than the R7 cord.

escort cord you will lose use of the mute button. Which you should not need for testing.

I think it is probably the power supply. The label tells me that is good for only 500 mA. Been using it for years without an issue on all kinds of devices. I guess the R7 is a bit power hungry. Thanks for the replies.
