Found out yesterday that the 1450 (and i suspect others) has a overtemp shutdown. I left my gps on the dash and went inside shopping and when i come back to the car the gps had a totally black screen when i hit the on/off button it come alive with a message saying it was shut down automaticly shut down due to excessive temperature, Dont ever remember anyone talking abot this. So from now on during the summer here i am not going to be leaving the unit on the dash for any length of time. It dont appear to have hurt in any, used it again today when no problems.
Amazon.com: Garmin Drive 60 USA LM GPS Navigator System with Lifetime. ChargerCity XT-Large Hard Shell Carry Case for Garmin Nuvi Drive Smart 51. Garmin Air Vent Mount. I had no problems using the windshield mount provided. Mixed with other colors and seeing which way to go at 1,200 feet per second. I have spent days trying to figure out how to get free maps to my old Garmin Nuvi GPS Nuvi 1200. To do this you NEED a newer Garmin GPS with Free Lifetime Maps I used Nuvi 1300LM 1: You make a backup of your old Garmin Nuvi 1200 GPS Files to your computer.

My model is a 1200 and I would expect that some mention would be made about keeping the unit cool, and there is: 0 to 140 degrees F is the operating range. The charger has a fuse, not a thermal cut-off circuit. So my conclusion is: Your model may have a thermal cut-off but my unit does not. I know garmin dont mention it in my manual either,(which they are the same manual) after it happened i looked for that,this the only time i ever heard of it at all. I would suspect if you did leave it up in the windshield for a while it would happen, i think this is just one of the features that Garmin dont talk about.Why? I just figured i would thow it out to the community and let them know that if it does happen to them what to expect.

So that wasnt a consern. BUT now at least i will put it on the floor away from that blazing heat, I would be more careful even with LEO or people around. My friend's gps was stolen from parking with security guards and CCTV. And of course it was never seen after it and nobody was apprehended. Police doesn't even bother to look for it, they just make 'report'.
And that was it. He had to buy new unit. Rafaeldrc wrote: Sorry, but I can't verify that a thermal shut-down exist by researching the net and Garmin.com.

So my conclusion is: Your model may have a thermal cut-off but my unit does not. It took some research, but I finally found the post in the GPSReview forum that addressed this. It points to an Amazon user review which references the nuvi 1350 User Manual. In the Troubleshooting Appendix: Problem: My nuvi does not charge in my vehicle. Solution: Your nuvi can only charge between 32 F and 113 F (0 C and 45 C). If the nuvi is placed in direct sunlight or a hot environment, it cannot charge.

So eventually your battery drains and shuts down even though you are operating with the power cord plugged in. From Garmin: Question: How does temperature affect the power and charge of my device? Answer: All of our units that have a rechargeable battery contain something inside the battery called a thermistor. If the thermistor inside the battery registers a temperature at or below 0°C or at or above 45°C1 (32 °F and 113 °F respectively)1 the charging mechanism within the unit will shut off. When the unit is operating outside of this temperature range the unit will operate solely off of the external power source and will not charge the battery.
When the unit is within the 32 °F and 113 °F temperature range, the external power source will power the unit and charge the battery. The unit's charger will always provide 100% to the unit and send any extra power to charge the battery.
As a preventative measure do not leave your device in direct sunlight. By keeping the device out of direct sunlight the unit is more likely to charge when getting into a hot vehicle. The best thing to do if your device is not powering on in the vehicle, or your battery is only lasting 30 minutes is to charge the unit overnight by using either an AC adapter or USB Cable attached to a computer. Charging from a USB cable connected to a computer will charge the unit at 30-50% of the rate of which it would charge if plugged into a 12-volt vehicle power cable. Temperatures within the vehicle generally tend to be warmer than the temperature outside of the vehicle.
Probably the easiest to follow set of instructions that I've seen are. As far as I can tell from reading, you'll need to get a microSD card if you don't already have one. As North America is quite large, I'd try to load a smaller map based around your local area first before retrying with a larger one.
There are actually of map created from OSM data for Garmin devices, but the site linked to from the above instructions is probably the easiest to use. It might also help to have a look at - there may be answers there that are useful.
