Lowrance keeps zooming out

Hi all,
I've got this annoying problem with my Lowrance globalmap 5150c, It's got navionics UK gold sd card inplace. I've chose the Irish Sea area, and all the fine detail is displayed when I zoom in, after confirming current position of course. The problem occurs 10 sec after zooming in, It just zooms back out showing the whole UK, I zoom in it zooms out? grrrrrr!
Any help would be much appreciated.

Not sure what the default map is in that machione, but if you take the Navonics card out, does it do that as well?

I'm thinking along the lines of a sticky "zoom out" button. If it does it with 2 separate maps it might rule out the Navonics card / map as a cause.

Other thought - Lowrance website - check you have the latest level of software. I updated mine and the echo sounder started to behave itself!

Not tryed without card yet, I'll try that later. I have used the unit with out the nav card before, and it gives a very basic outline of the full uk.
The unit came with the boat when I bought her, with no software update connectors, and I purchased the sd card just over a year ago, It was working fine the other month staying zoomed in whatever distance, I think I've done something in the menu, when I changed statute miles to NM, and changed range rings and tracking, I just can't get it to stay zoomed in.
I hope its not a sticky button.
many thanks.

I've had a couple of problems with stuck buttons (LMS-520C). Usually salt or other debris getting between the button and the conductive contact. Power the unit down, dribble a little fresh water over the keypad, and simultaneously (repeatedly) push and twist the buttons for 10 seconds or so. More water, and repeatedly push and release.

Might help; might not.

Cheers for the fresh water trick, I'm going to have to try that if all else fails, I'm a bit worried of causing more damage though.

Buttons are sealed. Unit is upposed to be sealed (it is, but is not really robust; the opening that will leak is on the side of the unit anyway.) Not really much risk working with the keypad.

Daft as it sounds, you've not selected "AutoZoom" or something similar in the menu have you?

Many thanks for your advice jky, I didn't have a clue of the waterproofing qualities to be honest, although I realised it must be slightly resistant as it's taken many splashes over the years, trouble is I didn't get any manual or advice when I purchased with boat. Maybe I should give it a regular fresh water rinse.

That's not a daft question to ask me Dave, sound's just like something I'd do.
However I took the sd card out the other night and give it a blow, and then tryed it out yesterday, after waiting for it to aquire position, It then showed the whole of europe on full screen, I then tryed split screen and zoomed in and hay presto it stayed zoomed to my prefered 1 mile range. I didn't get round to trying full screen again, as I generally only use this when reef fishkin. so I'll try that later.
That's if it still works cus it got a right swamping yesterday, whilst filming around Skomer. And now my Hummin fish finder don't work
