Hi All,
I have just installed a Navman 6507 GPS/sounder combo. I want to load up my waypoints and learn how to use etc. My concern, and question is can I switch on the unit and play with it in the drive way? I have heard that if you have the sounder on out of water it can heat up or do damage. I can not find any thing in the user manual about it or about switching off the sounder.
Any help would be appreciated.
