SOURCE: My Garmin nuvi 1300 brightness problems

I spoke to Garmin Support about this issue. There are 2 settings for contrast on the nuvi 1300. You need to set the contrast while it is plugged into the vehicle, and also while it is unplugged from the vehicle. The reason for the 2 settings is to save the charge of the battery while it is not plugged into the vehicle or power source.

SOURCE: garmin nuvi 250 keeps losimg signal

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:
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

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. I hope this was helpful for you. Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question!!!!!!!!!!!!!!!!!!!
