3597LMTHD and the heat

I use a vent mount on my 3597LMTHD. I have the vents pointed down and partially shut off so it doesn't seem to affect it. I have not had any problems with it overheating or getting hot. When I remove it from the mount after using it all day, I don't notice that it is any warmer than any of my older nuvi's.

I do leave the mount permantently mounted to the vent, as it is too difficult to remove and reattach. I have a hat that I throw over it so it is not exposed to the direct sun and is not visible through the windows. The cord routed under the dash so it is not visable either. I know there is a risk that some thief will realize what my hat is hanging on and will break in and steal the mount. Normally I take the nuvi itself with me and don't leave it in the car.

What if you actually need to use your heater or air conditioner though? Doesn't the gps block the air flow?

The 3597 gets hot setting on my desk in the house so I wouldn't worry to much about it feeling warm. I also use it beanbag mounted on the dashboard in Phoenix heat and have never had a problem with overheating.

The GPS with an airvent mount shouldn't block the airflow to any measureable extent (my guess) but will redirect the air.

Used with AC, the cool air should actually help keep the GPS cool. In winter, if your heater provides really hot air, my thought would be to turn off the air flow to that specific vent.

I've had my 3597 connected via an airvent mount for a couple months now and have no issues with GPS operation, including running with heat, AC, and outside air.

There's a testimony to its ability to handle the heat...if it will survive in the Phoenix heat, it will survive anything

Thanks Craig and Alan, I will probably give one a try in the future. Now that I know it will stand up to the Phoenix heat, I'm ok with it for now.

But remember that t92 and his nuvi spends half his time in the Frozen North so his 3597's annual average temp is way below that of Phoenix.

I forgot about that, Canada right? How can one live in the two extremes?? I guess it's winter in Phoenix and summer in Canada.

t92 how hot has it been when you have your 3597 on your dash?

No more ice bridge until winter--the ferry is operational now.

We are in Arizona from early October to mid April. MAX temps are in 80's and 90's, That isn't really the point however. My 3597 is on the dash and the car is either parked or being driven in the sun all day, every day, and the inside of the vehicle can get well above 100 degrees on a regular basis, especially as we have a sunroof that covers both the front and back seats. We are comfortable with the AC on but the Nuvi is just setting their in the sun.

As I've said, the 3597 gets hot when out of the sun and I've never had a heat problem with it under any conditions.

By the way, we don't live in the "frozen north". We live on the Pacific ocean where it hardly ever snows. It's the 5 months of rain in the winter (think Seattle) that drives us to Arizona. Summer in our area is like February and March in Phoenix. Very pleasant, usually sunny and no "big extremes". Again the 3597 spends the summer on the dashboard with no heat related issues.

And Dawson City is approximately 2000 miles north of our house.

It sounds to me like Craig is trying to cause trouble around here
