You're not alone - nearly all the anti-reflective coating has come off our 178c after 8 months.

I'm going to contact Garmin when I've got a minute or ten.

Then again, if anyone's aware of a cheap, durable and effective after-market a/r coating that can be applied by the ham-fisted, I'd be very interested.

It'd really reduce the glare - but somehow I doubt the legibility would improve...

The loss of the anti-reflective coating is often talked about on the US forums. Is seems to be particularly bad when in direct sunlight....just like Arran ....there doesn't seem to be a satisfactory aftermarket cure. Most folk talk about a stick on protective film which, apparently, is also a bit anti-reflective. I think the idea is to put it on when the unit is new. However, if Garmin don't have a solution which doesn't cost you, a good polishing with T-cut or Brasso will probably remove the remains of the coating. You can then live with the shine or try the stick on film. I've seen the film advertised on Ebay.

This is not my usual type of advice since I've not tried it so you're on your own. I've polished plenty of things with Brasso, though.

I was always very carefull with my screen and always washed the screen with water and wiped with really soft cloth and camera wipes (which I actually kept on board), the screen was never in direct sunlight unless in use. I think that when the GPS is on it's not too bad, just very unsightly when switched off.

Andy

Try wiping it with a normal glasses cleaning cloth, like you get with a new pair of specs.
It may be too late as your coating appears to have become patchy already.

If you've not got one, I can let you have one with RAYMARINE printed on it
They are supplied with all Raymarine displays as a cleaning cloth.

If you end up taking the coating off altogether the film JW mentioned is supposed to work very well on computer screens, so would be worth a go.

Andy, is the film damaged or is it just marked with grease and fingerprints? If it's just marked try using some Fairy Liquid in a small amount of warm water and then rinse it off. Wipe gently with a kitchen towel, use a new sheet for each wipe. I use this if I mark a camera lens, computer screen, CDs and also on me specs.

Andy I just had this happen to my 178C I actually decided to remove mine completely and used window cleaner. It does not make any diffrence as far as I can see as I can still see the screen clearly in sunlight.

I hope my Raymarine will be ok - the screen was a bit grubby so I was going to clean it - then this bloke comes around from the RNLI to do a free safety check - before I could stop him he started rubbing at the screen with his grubby hand to clean it!!!

After my very loud comments he won't do it again in a hurry....
