SO we get in the car ands its 78...after driving for about 30 minutes with the air on the amb says 70........wierd..we were in the same area the whole time. Do you guys get a consistent accurate temp??

 

As with most vehicles with outside temp readings, you typically need to drive around for at least 5-10 minutes (depending on where the sensor is located) to evacuate standing heated/cooled air and cool down surfaces near the sensor. For instance, here it has been in the mid 90's but the car reads over 102 (sits in the sun during the day) when I first get in it. About 10 minutes later and it is within 2 degrees or so of other thermometers/weather readings.

 

Yes i agree!

 

What jjs said. My temp readout is pretty accurate after a few minutes of driving.

 

anyway to make the amb stay up all the time, instead of just for 5 secs?
