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
