Re: 334CiGPS messed up
The LMS 334c is an old unit that was even before the LCX units. The 520 replaced the 334, now the HDS 5 replaced the 520.
As for a hard reset, with the unit off press and hold down the ZIN and ZOUT buttons and press and release the power key. Keep holding the ZIN and ZOUT keys down until the map of the US comes up, then release them. Now the unit is reset to original factory settings. Beware that this will also erase any and all waypoints, routes and trails you have saved along with all overlay data and custom settings you have made.
