I'm getting my parents a GPS for christmas to go in there motorhome.
Their motorhome is 24volt. Some people have said that the power cord will be fine for a 24volt as it converts power down to recomended wattage, others have said it will blow it up?
Does anyone here know?
Has anyone got a 24volt vehicle that uses a GPS?

Last thing I want to do is blow up a new GPS.

They will need a 12 volt outlet for other things as well, so run a couple off the house batteries for the GPS and others as needed. Some power cords will cope, some wont, it will be marked on the cord!
(I guess it is a coaster?)

They can then use their phone charger on the road as well!

Already have 12v outlets in the back. Trying to avoid a 6-7foot extension lead to the dash where the GPS would be used.

A simple converter to change the 24volt to 12 volt is also available. these are not too big or expensive and will fit behind the dash. Try a twelve volt specialist or Jacar.

Some have a 12v supply to run the dash /radio etc. so you may find a 12v supply otherwise you can get a 24 to 12 voltage regulator they handle about 6 amp and are quite cheap from Jaycar and others I guess probably also ebay alternately just run a supply from one battery

Going to Jayco tomorrow to see what they say.
I did suggest that they might need to convert the cig lighter to 12volt.
Everthing on the thing is 24volt. Dash, front and rear lights, radio, etc.

Reminds me of my first Patrol which was 24 as well. Did not find that out till I blew up a stereo. Had to run seperate wiring for my accesories.

FWIW
I have 10 or so original Garmin DC ciigarette lighter type power adaptors here from various handhelds and vehicle nuvis.
They are ALL labeled "10-30 VDC".

Any Garmin nuvi GPS will run perfectly in your parents motorhome without modification to the supplied adaptor.

That is good to know. Thanks for that info.
I have a Nuvi myself, but as I don't have the original plug there was nothing written on it. Maybe the package it came in, but that is long gone.
