Power supply for using your Garmin indoors

Hi All

We have a Garmin GPSmap 550s - have any of you found or created an indoor power supply - I'd like to be able to porgramme in our waypoints etc before setting off and without having to sit in the boat

Are you planning on inputting them manually?

Another option might be to find a data cable that (I think) may power it from the USB on your confuser, then download yourself a coopy of EasyGPS ( http://www.easygps.com/download.asp ) and you can input them at leisure - and a LOT more easily - then with about 2 clicks squirt them all down the wire into the Garmin.

think for most garmin sets you can buy "power only" "data only" & various other combinations of leads & plugs / sockets for them. I bought a "Power & data to bare tails" that I installed on the boat to get it to feed the VHF in an emergency.

I use an old 12vJetski/ Motorbike battery & Garmin power lead with bare tails on the wire wound round the terminals. .

The GPS has no idea its not on the boat so you can all the normal stuff , but sat on the sofa.

Nice tip!

Other way is to get a 12 (or 13.8V) regulated power supply from Maplin or similar. Not expensive and handy for checking any 12V equipment.

You can also use Garmin Trip and Waypoint Manager (or something like EasyGPS as suggested earlier) and save the routes onto SD card. They will need to be in ADM format to be read on the Garmin. Something to try out when it's not critical!
