Guest tak1 Posted June 2, 2001 Have any of you guys run your 315, or other gps with the cigaretter lighter adapter without batteries in the unit? LK Quote Share this post Link to post
Guest topografix Posted June 2, 2001 I do it all the time with my 315. For long trips, I usually use the 315 as the driving GPS, and don't bother putting batteries in it. Once I get to the trailhead, I turn on the eTrex and use it for the hike. Quote Share this post Link to post
