Help with Lowrance H20 and LM chip

[Smails]

I bought an H20 this summer and put my lakemaster chip in it today. The unit locates just fine but I don't see any lake detail when I move the cursor over to Prior Lake and zoom in.

Is there a set-up procedure that I need to follow so the unit will recognize the LM chip?

Thanks for the help!

Mine shows Prior just fine. Are you sure it's on your chip? How do the other lakes look?

we had trouble getting out LM chip to read in our H20C last year when we got it too. make sure the chip is placed correctly in the unit, behind the batteries. we thought it was supposed to get in one way, but turns out, it went in another way then we thought. as soon we we figured out the correct way for the chip to sit behind the batteries, we were golden. i am sure you are encountering the same problem we did too. read the instructions for how to place the chip in the unit

Wish,

Yes, Prior Lake is featured on my lakemaster chip. I was just fishing Prior on Friday afternoon and my LMS-480 was working perfectly with the chip. Today, I put the chip in my H20 and moved the cursor to Lake Minnetonka and zoomed in but didn't see any lake contours either...

JWM,

I am positive the chip is installed correctly. The metal pads on the bottom of the chip line up perfectly with the metal contacts in the H20. I am installing it exactly as they recommend in the owners manual.

Thanks for the suggestions but it's got to be something else. Could the H20 be faulty since it doesn't recognize the chip?

if you know you have it installed correctly, the lakemaps should just come up. maybe take the unit back to the place you got it and politely ask if they could show you how to get the lakemaps showing

1st off do other chips work in your H2O? I had a bad chip that my H2oc wouldnt read. Got a new chip and it was fine.

Northlander,

The chip is good. I was just using it in my boat (LMS-480) on Friday afternoon. I think I have a bad H20.

Problem solved - the card reader on my H20 was bad. I picked up a new H20 this weekend at the ice fishing show and my problems are solved. Just need a little more ice and I'm set!!

Man, I just posted a similar problem with my navionics chip...so I thought. Maybe the reader on my H20 is the problem. The H20 is only a few months old. Anyone else having this issue?

Did you select Navionics as your "map choice" under "map data"?

I found the Lowrance web-site helpful for troubleshooting although it didn't solve my problem.

I'm glad you found the problem. Did you have to buy a new one, or would they let you return it?

Thanks, I will check out the Lowrance HSOforum.

Once there then select the correct map for your area.
