well boys you guys have alot better luck than I did with the Lowrance folks...I bought a brand new lms522c igps and it worked a total of 2 days....no rain on either day. Turn it on and the screen would lite up and then verticle lines across screen then about half the screen would go dark and then the unit would lock up and not turn off. You had to undo the power cable in the back to turn the thing off. I already had one lms522c on the console and I had traded a x510c and some cash for the new unit because I like the first lms522c so much. I go back to the dealer..."not our problem call Lowrance". So I did. I was on hold 56 min before I got to talk to any body but the guy I talked to first tried to help me. Sent me to there wed site for a free download of updated software and some rebooting directions. Well none of that worked so I called back. 1 hour 22 min I get to talk to a very nice lady and she gives me instructions on how to mail my unit back to them and a "incident" number. She told me it would be 4-6 weeks before I got my unit back. This was the second week in March. April the 28 or 29 can't remember for sure I got a box from Lowrance...I was ecstatic...for a while....come to find out they had sent me a 520 instead of a 522....the 520 has no internal gps and since the units look identical except for the numbers I spent a whole day trying to find out why "gps module not responding" was showing up on the screen. Well I had to call Lowrance again 47 min this time but at least I got to talk to the same lady and she sent me a shipping lable and a new 522c igps overnight but since this was on a Friday I got it the following Tuesday. Well I have it back on the boat and it seems to work ok...I haven't had it on the water yet but you better know it is going to have a baggie over it if it ever starts to rain. The folks were nice on the phone but I missed most of the crappie season this year. I hope it works as well as my first one did/does. If not Hummingbird or somebody else is going to have a new customer. I can't do this again and remain sane or in good humor.....brim
