Well done Malthouse

[two stroke mick]

I have to Complement Malthouse on his after sales service. I had a intermittant problem with My garmin 550 chart plotter. I sent it to Malthouse so he could investigate the problem. After some extensive reserach the proble was found and fixed with no fuss.

Note

Any owners of the 450 or 550 ior 555 garmin chartplotters with an port for an external aerial you should block it up as it can cause the unit to lose the signal

Same problem with my 420. I think I wrote a post about it in "Electronics"

Anyone know if Garmin have a position on this?

If that is the hole on the back next to the socket for the tranducer cable, the one I bought recently from Seamark Nunn has a rubber cover that fits over the aerial socket. Maybe that is how Garmin solved the problem on the latest versions.

Thanks Two Stroke!

Yes indeed, Garmin are now shipping rubber covers - but beware these can trap water inside.

The units are a great piece of kit, but they have slipped up slightly by having both internal and external antenna options in one model. Garmin are, as far as I have been able to tell not admitting to a design fault (yet).

If you are buying one of these I would suggest you make sure the rubber cover is included, not so much for the unit's protection but to reinforce the point to the supplier.
