eagle 480 gps problems

the unit will not read the navionics chip. it turns on and all my waypoints are on the stock back ground map. anybody have any thoughts on this one……………tom fellegy

Tom,

First thing to do, is to backup your waypoints to a SD card. Did you try the simple stuff. Remove the card, verify the contacts are clean and not corroded? Did you verify you have the correct datum selected in the setup?

I would try removing power completely from the unit. If reseting everything doesn’t work, you may try the “reboot” command. I’m sorry, but I don’t remember the button combination that you push for this. Can any else help with this??

Hey Tom, call Lowrance…they helped me this past summer with a problem. They have a great bunch of tech’s once you get your call through to them. It might take 10-20 minutes on hold sometimes.

Did you turn the map on?

Tom, What steps have you done so far? Are you familiar with Navionics maps or is this new? Reason I ask is some people don’t know you have to tell the unit to read the map. If I recall correctly, you’ve had the chip for a while now.

How to pull up a map… (Use the Lowrance notes) There are some other tips on the left side at that link.

If that isn’t the problem, you may need to to a reset on the unit. Take the chip out and make sure you have backed up all waypoints or you will LOSE THEM! Press the PAGES and POWER buttons at the same time to reset the unit. Then try the card again.

it doesn’t even show the the map in the menue. the only options are the miami test map and the stock background map. i will give lowrance a call and see if they can help. thanks for the help, i will keep you posted……….tom fellegy

Ahhh, So it’s not reading the card at all. A restart may solve the problem. Let us know Tom.

right now i am packing up and going to build a deer stant today. i will try a few things tomorrow.
wade, it has been a few years that i have had that chip now. will the lake master chip work in that unit? if so i will try that.

Normally it does, yes.

what size mmc card do i need?

is there any history of the navionics chip going bad? the navionics chip does not work, the eagle 480 does not even recognize the navionics chip. i put my lake master chip in and it recognizes it right away. is it the eagle intellamap 480 or the navionics chip. the chip is about 3 years old if that means anything………………tom fellegy

Could the chip have been erased?

I have the same problem with my Eagle 480DF. It does not recognize the Navionics chip, which is brand new and I just updated the data on it so I know the chip is good. Has anyone found the solution?

That is a VERY old unit I would almost guarantee the new chips are not compatible with units that old. Might have to go to the Navionics website and find compatible units for each chip or contact support to get your answer though.
