How do you enter coordinant into GPS to find a

The 1212 will not do what you want it to do...its just not capable of taking longitude and latitude.you can get copy of your manual for your 1212 here

.probably the easiest way around this problem, is to get the address somehow (was there a phone number provided with the rv location list)

if you know the approximate location, you can use google maps to zoom in and get a street address
google maps here

you could also use google earth if you have it..if not, you can get it here very cool even if youll only use it once.

you can enter longitude and latitude in google earth

let me know if you need more help

good luck
