sc1984 Posted September 21, 2015 Report Share Posted September 21, 2015 Hello, Bought a used 8100NEX off ebay. Didn't come with any cables but got a decent deal so couldn't complain. I installed it and works beautifully, until my antenna came in the mail and hooked it up. Second I installed it a message came up saying GPS Antenna problem detected. According to the manual it is a short circuit. So, is there anyway to confirm the short circuit with a DMM or something? Just don't want to waste time returning and shipping out another antenna if the head unit is the problem. Any help would be appreciated Quote Link to post Share on other sites
