Hondam, Thank you for the reply. I will get you the serial no. soon so you can take a look at it. The only problem is, the $500 i would need to fork over to upgrade on a waranteed product. Shouldn't lowrance just send me the upgrade under the warantee? i have troulble spending another $500 on an already $1800 radar that i have used 5 times and had nothing but troubles with. i do have it paired up with an HDS-10 that i am happy with its performance. for me to totally scrap lowrance would be a rather large expense, and was hoping to avoid this is possible, but it still is on the back burner.
