My magellan turned on one time and napped, crackled and popped and shows that it has loaded but it nothing will come on. I can't use it, what do I do?

If it’s an iPhone? Do a hard re start on it!
Press both home button & turn off & on switch at the same time. Wait till the screen goes black (it is now off).
Wait for 5x mins or so, then turn it on as normal. This resets the software of the phone, but does not delete any of your data

don't leave it on and have it looked at---most likely is if it uses a lamp that may be the problem but if not it may be in the power supply.

Crackling and backfire is nearly always lean on fuel condition...
open your air fuel mix screw tiny amount at a time and test to see if helping this should clear up the popping..
Please note if you need to open the air fuel mix screw more than 3 full turns from fully closed then the easiest solution is leave the air fuel screw at 2 turns out from closed and increase the size of your pilot jet by one or two sizes.. they very cheap to buy few dollars each.
I would suggest if your only popping and crackling a little then small adjustment on the air fuel mix screw will cure it for sure
Being YZ I find an occasional pop or backfire when de acelorating is exactly how they should be if you don't get a pop or crackle every now and again then chances are it running to rich.
but if it is regular occurance then definitely needs fine tuning or larger pilot jet installed
good luck regards Jamie

Maybe rca cables bad

Hello There, I have a Magellan myself, besides me knowing some things or two about GPS'S

Give this a try, seems to work for me and others most the time.


Try this for me to see if this works: Let me know. It needs to be rebooted. Turn off, by holding off button down. Then once it is completely off, then turn it on, BUT when you go to turn it on, keep on button depressed, all the way until it turns on and then some for about 15 seconds, now you just rebooted system. Let me know, if does work, please click on the thumbs up to showed your a happy customer. Thanks Mike

Good afternoon.
I also have 2 promark 3 receivers and at this point nothing could be predicted, one of them does not start, the screen turns on the light, but nothing appears on the screen.
Is there someone here who can help?
Thank you

I've seen some comments that you can't turn NAP off once it's set.

You can turn off NAP by holding down the NAP button for a few seconds again once the clock has exited NAP set mode and is showing the time. When you first hit the button, it'll go back into NAP set mode (probably showing 0:20) but after a few seconds, you'll go back to the time with NAP off.

Trick is, the button's a little quirky, and you have to hold down just the edge closest to the back of the clock. The middle of the button or any other edge just throws you back into NAP time adjust but never turns it off. I have no idea why--must be a design or manufacturing flaw of some kind.

You have to "double-click" the "NAP" button. And on the second "click," hold it down until the "NAP" light goes off.
That worked for me three times in a row, at least.

I have a Solution for this Problem,

Being solid stae electronics - there is little or nothing for you to do
With this type of thing it works or it does not.
