Hello. Installing a map, I "found" on the web on my eTrex Venture Cx. The map works but, gps coordinator is not consistent with geocash and my cell phone. Have heard that you can zero a GPS or calibrate, how does it work? Then how do I do a factory reset on it. I know it's page button and enter- button as well as on- button. However, only a menu that is gray with text on it comes up. And when I touch the buttons where it indicates which buttons I press. Can i do a factoryreset there from? Grateful for answers
