I have Rocz power supply but when used with a Garmin USB cord the GPS likes to think it's getting down loads and cycle back and forth. Guess the USB cord isn't equal to a 12v car charger cord.

When I use the plug in car charger cord the GPS works perfectly but the cigarette plug likes to come loose while riding so my maps keep resetting.

Anyone have a good power source option for this?
 
Common problem. Go to GPS city. They make a cord specially to prevent this, just a couple of dollars. I got one for mine, has something to do with the pin configuration. There is also a way to cheat this with a regular usb on YouTube. But didn’t want to deal with it. Just get cord. I’ll see if I can find link for ya.
 
Upon further reading that’s the cable you need! I use mine with rocks power supply and it’s money!
