Nuvi 3790LMT overheating?

 

Rather than buy new maps, I am considering moving from my four-yaear old Nuvi 650 to the Nuvi 3790LMT.

Looking at reviews of this GPS on Amazon.com and cnet, I repeatedly see concerns about the unit being extremely hot. Almost too hot to touch.

Recognizing heat to be one of the worst "enemies" of electronics, thought it would be better to ask the pros here instead of relying on comments from the hoi-polloi on Amazon.

Any 3790LMT users have a problem with very hot units???

Thanks a lot. Also welcome any comments anyone would like to offer on that Garmin unit.

3970

I got mine when it first came out so I have been using it and traveling with it for a while. It does get hot--black case + black dashboard + South Florida= HOT. But never so hot that you could not carry it. The heat never caused it to reset or act crazy.

It is

It is normal for the back of the 3790 to feel hot, whether in your window on a hot day or on your desk in the house.

Have about 17000 miles on my 3790, about half of those in Arizona. Had maybe 3 resets none of which I'd attribute to heat.

Nuvi 350, 760, 1695LM, 3790LMT, 2460LMT, 3597LMTHD, DriveLuxe 50LMTHD, DriveSmart 61, Garmin Drive 52, Garmin Backup Camera 40 and TomTom XXL540s.

No problems with any kind of over heat.

My 3790t is warm to the touch during and after a twelve hour shift. No reboots or any strange anomalies. Got my 3790t late March and I’m as happy as can be. smile

Not Hot

I've had my 3790LMT for about 6 months and it is working well. Not hot at all.

I never leave it in my car and my A/C will be running during hot weather.

Summer is starting and that will be the true test.

Nuvi 3790LMT overheating?

Thank you for all your comments and feedback, on the basis of which we ordered the unit from Crutchfield. Believe my wife said it was on sale there.

We spoke to their tech support folks about our concerns and they told us their policy was a full refund for this unit for a period of 60 days, as long as the unit isn't marred in some fashion.

It arrives Tuesday, free shipping

Thanks once more for taking the time to respond.
