I ve got a 550 and there's a bit of a major design fault if you don't flush mount them or leave them exposed to the elements when in use. The external GPS input, if not used (as theres a built in atenna) let's water directly into the unit and then fries it! Simple fix with a waterproof cap, but Garmin don't supply one. I ve used a blanked off piece of fuel hose as a temporary fix.

Very many thanks for this info! We have encountered it but Garmin have been very tight lipped about whether it is a design issue or a one off.

None the less, they are an excellent unit.

Mine's flush mounted but I think I'll seal it anyway...Whilst being doused with sea water might cause an immediate failure I'm sure exposure to sea air over a longer time won't exactly have a beneficial effect either

Wow. Glad you posted that. I'll not be using an external aerial and mine's bracket mounted so I think I'll bung the thing up with silicone sealer. The main data cables make me wonder a bit too, especially on my old GPS126.

Anyone know of a better deal on the 550s than Redcar electronics at £478 inc transducer? I too am in the hunt for one of these.

Either Redcar have some old stock at the 2008 price and they are happy to sell it off, or they have not updated their web site since the latest of many price increases came through.

I suggest you go for it.
