With all the bad reports on BBC about up dates on the bird forum, there is no way I will install one on either of my Helix 10's. Your best bet is to find someone who has the version of software you were using before the up date.
Mine did the same thing just took out my map card and disconnected all but the power wire and reset to the default settings. Then it all came back. When mine did it just one side of my side imaging went out and the maps weren't working. Went back in and set it back to the way I had it.
THANKS GUYS FOR ALL THE INFORMATION THIS IS THE THING I LIKE ABOUT THIS SITE YOU CAN ASK A QUESTION AND YOU GET GOOD RESPONSE THANKS. I RESET MY DEFAULTS AND GOT 90% OF MY STUFF BACK ESPECIALLY MY GPS SPEED TIME STILL HAVING ISSUES WITH SIDE IMAGE BUT I CAN DEAL WITH THAT. GLAD I GOT MY GPS BACK. I WAS ON CHICK YESTERDAY WITHOUT IT. AND YOU KNOW WHAT HAPPENED RAN A GROUND
Thanks pop r for infro my side image went out on one side also on the left reset defaults got MY GPS back but side image still one side I tried it a couple times did yours work first time I can live without side image but it's good at times any more suggestions THANKS
Sorry I just saw your question. I plugged in a different transducer and it did the same thing. I was still out on the water and reset my defaults after unplugging the one I was testing to see if that was it. After reset I plugged the old one back in and that is when it started working. I don't know if unplugging it had anything to do with it or not.
