The Wayfinder wireless car thermometer has an ice alert.

The Wayfinder wireless car thermometer also offers an ice alert function that notifies the driver of possible ice conditions on the road when the outside temperature has dropped to 35F and to proceed with caution. It also has a holographic display screen for easy reading during the day and also includes a bright back light for reading in the dark.

The Roadpro car digital thermometer has many added features.

The Roadpro car digital thermometer offers more features such as a compass, clock, inside and outside temperature, back light, and an ice alert. It is easy to install and can be installed on your dash using Velcro.

The Wayfinder wireless car thermometer has quite a temperature range.

The Wayfinder wireless car thermometer covers a broad temperature range up to 155 degrees. It is able to read temperatures as low as -35 F all the way up to 120F. Also it includes an useful and accurate compass. This particular model comes with the ability to use complex algorithms to consider the metal in your car and give a precise compass reading. This same technology is used by Ford, GM, and Chrysler inside of their factory built vehicles. Which means you know it is accurate and reliable. The compass has a large arrow, 8 cardinal points, as well as a digital numeric reading.

Easy way to install car thermometer external sensor.

Installing a car thermometer external sensor can be done a couple of different ways. For models which are positioned on the dash, run the wire where the dashboard and the windshield meet, and use a credit card to push it in. Run it to the door, and place the external sensor inside the door jam so it has access to the outside air. But don't leave it out so far to where it will be hit whenever you get a car wash. Another way to install the sensor is to run the wire through the dash, and use wire ties to attach the wire to the car frame away from the motor. Come down between the radiator and headlight, and attach underneath or inside the bumper, make certain the sensor is protected from the elements. It's as simple as that.

Where to put a wireless car thermometer external sensor.

The Wayfinder wireless car thermometer works by using an external temperature sensor to get outside temperature readings. The external sensor is not difficult to set up. It is best to place it either inside the door jam or fasten it to the front bumper. A number of people find placing it right behind the front license plate does work really well for reliable readings.

Popular car digital thermometer models.

Two popular car digital thermometer models available are the Buler and the Roadpro.

The Buler car digital thermometer is basic and just shows the outside temperature. It has a rectangular shaped face along with a four foot wire for the external temperature sensor. This model does not have extra bells and whistles but will provide an accurate outside temperature reading. This can be attached to the dash with double sided tape. Several owners have cut a rectangular hole in their dashboard and inserted it in it to get a factory installed look.

Watch the outside temperature change with an auto thermometer.

Last summer we drove from Los Angeles to Palm Springs. The actual trip is around 125 miles or roughly 2 hours on the highway without traffic. When we left Los Angeles, I looked at our factory installed auto thermometer for the outside temperature. It was in the mid 80's as it was about 10 o'clock at night. I kept a close watch on the temperature as we drove through Pasadena, Montclair, and then Ontario as it still remained in the mid 80's. When we approached Yucaipa and started climbing up the mountain, the temperature began dropping to the low 80's. When we came down the mountain into Banning, the temperature started going up quickly. It was now back to mid 80's, then low 90's. In Cabezon, it was mid 90's and still rising. When we approached Palm Springs, it was at 97, 98, 99, and then 100 degrees. We pulled into Palm Springs at midnight and it was still 100 degrees outside. This all was made possible using our auto thermometer.
