How to find the polarity for my Magellan Explorist 210??

[cyrjm]

I bought a universal car adapter at Target to use with my Magellan Explorist 210. It is a 12v unit that has interchangeable "tips" to plug into the USB/power cable but needs to be set at the correct polarity to ensure it doesn't explode. I've looked through the documentation and online with no luck...is it - - + or + - - ?


Thanks for any help!

There usually is a diagram near the connection with a plus or minus sign pointing to the center pin.




The eXplorists have reverse polarity shutdown protection so that the device will not start up with the incorrect polarity.

Thanks for the reply...I looked on the USB cable and inside the battery compartment before posting this question and could not find it. Do you have any documentation that says the Explorist has reverse polarity protection?
