Garmin 2620 gps

Most GPS problems - Hangs, frozen screens, problems acquiring satellites, ETC, can be attributed to the device not having the latest firmware installed.
This firmware enables it to communicate with the satellites - but if they aren't speaking the same language they get confused easily. For Garmin GPS Automotive units, Garmin has you do the following before sending it in for repairs:
1 - SOFT RESET
2 - HARD RESET (CLICK HERE to see instructions for either reset)
3 - UPDATE the device using their WebUpdater software (CLICK HERE for that) Garmin is the only company that offers repairs AFTER the warranty has expired. They offer a FLAT RATE REPAIR service for units no longer in warranty. For Other GPS units please consult your owner's manual or their support site - as each model - and even manufacture dates - can lead to different reset procedures. TomTom
NAVIGON
MAGELLAN NEXTAR does NOT offer any types of Firmware or map upgrades or repair services. Instead - they have an exchange program to update to a new UNIT for around the same price as a repair would be. CLICK HERE for more on that. WARRANTY on most GPS devices is 1 year from the date of purchase. Broken screens are considered ABUSE - and not covered under warranty. Finally - If your unit is on the charger for HOURS, You've tried both the car AND USB type charger, and you turn it on... it stays on for a minute (or so) then powers down or never comes on at all - the battery has lost it's ability to hold a charge and must be replaced. Looking around YouTube - you can get a tutorial on how to CAREFULLY crack open just about any GPS. The tool(s) necessary typically are included with the battery purchase. Typically batteries run about $25 +/-. NiCd batteries are meant to be energized once a month so they keep active, and don't build up deposits that lead to their premature failure.
