Just had a new 1198 installed, i had a lowrance which had a navionics chip in it. I got the card last year. So i took it out and put it in my humminbird. It will start up but after about 20 seconds, the unit shuts down and restarts, it will keep doing that until i take the card out. Just wondering if anyone has seen this problem before, or if anyone has any advice. I was in my driveway also. I am heading out onto a lake tomorrow, and i will give it another try. I also have a 997 on my TM, which i did not try it in that unit. Any help would be great, Thanks
