I don't mean to offend you, but do you know how to adjust the backlight and the contrast?

none taken, yes, the backlight is on high and the only light that comes on at all is when powering on there is a flicker, then nothing. Has a laptop do that once and the light bar was shot.

Yes, my 498 also did the same thing and it was only a month or 2 old. Really weird how i cured the problem. I plugged it into the wall mount cable at home and it has never happened again

Call Garmin. They could get it back to you in much less than 2 weeks. Even if they charge you, consider what you could buy for the same money. The 498 is a very, very fine unit.

I feel the same way about mine as sandyda does. Just FYI, if they charge you (which they may not) the current flatrate for the 498 is $175, you pay shipping to them, they pay shipping on the return.

(One thought re. the problem: have you turned off "Auto Backlight Adjust" in the System Menu? Probably not relevant if you are seeing no light at all from the backlight.)

Check this out, I sent it back to garmin, 170.00 later I have a new (refurb) I took it on the river this morning for a maiden voyage and blam worked for about 10 minutes and the backlight goes out again. My voltage is 12.6 while motor off and 14 with motor running. Black is connected to neg and red is connected to pos.

This is what I am doing to turn up the backlight. I power the unit up, the backlight flashes then goes off, then I press enter for "I agree" then I [press the power button to get the backlight settings. I can see that the backlight is all the way up but there is no light. aaaaaaahhhhhhh!!!!!

Any ideas?

Ooooops! Damn, that's frustrating. Super odd the same problem twice in a row with two diff units, but as you say, if the power is connected, what else could it be? Back to Garmin again? (Yeah, I know that's a crummy suggestion, but about the only one I got.)

Reason I suggested the "auto backlight" setting when talking about your former unit was that my 498 does not seem to do what I'm describing, but years ago with an old Garmin (220, I think) the "auto backlight," if it was turned on, would actually override my setting in the backlight setting, even though it wasn't supposed to. Had to keep it (auto) off to get the "regular" adjustment to work. Well, that was just a longshot. You probably got a defective replacement.

3 of my Garmin 545s went back to WestMarine because backlight failed, all within 4 mos period, they just swapped them out at the store.

Same problem with a 178. I can't decide if it is worth sending back to Garmin.

sandyda, either you work for Garmin or are living in the past. Their quality has gone way down hill recently. I had a terrible experience with Garmin and will never buy their substandard products again.
Please read my post from a little while back.

I still haven't heard anything back yet about the cover.

Yes you do (have an Automatic Backlight control.) Not surprising you don't know, 'cause it's not easy to find. Press and hold the MENU key to get the Main Menu. There, select the "System" tab. Then select the sub-tab (to the right) "General" (it will probably be pre-selected.) Once there, one of the choices is "Automatic Backlight." You might have to scroll up or down to see it. It is an on/off toggle. You want it off. If you've got the manual, it's on page 65.

This is probably NOT your problem, since it sounds like your backlight is probably completely dead.

Interesting turn of events.

Called Garmin today after emailing them yesterday w/ no response yet. Tech had me go to auto backlight but it was off. He then had me reset to factory settings. This brought the backlight back on.

Problem solved? I dont know. Why did the backlight go out to begin with? I didnt change any settings. And was that the only issue with my first gps? If so they charged me 170.00 for nothing. just to exchange units. Ill email them and ask for my money back or some sort of proof that they tested my old unit.

So if you have this issue try reseting all factory settings.

Well, great it got worked out for you. On these older discontinued units, I doubt that they test the incoming ones. They probably just toss them or scavenge them for parts, and send you out a new one. I'm afraid, too, that they will probably keep the $170. After all, you did get a new unit. Also, with the flatrate, there isn't usually any provision for a "free" test of a customer's out of warranty units. IT's generally a send it in and pay the fee deal, no matter what is (or isn't) wrong with the old one. Of course, for newer units under warranty, totally different procedure.
