A friend at work keeps asking me to recommend an aftermarket in-car thermometer that measures the outside air temp. Apparently it is for his wife. I guess they do not want the little items you stick on to your side view mirrors. They tried those and found they fell off or were hard to read or some such. Anyway, any tips will be appreciated.

Thanks.

put it on the hood and it will look like one of those tacometers

 

old school!

 

The only way I see to do it cleanly would be the aftermarket autodimming mirror route. Like this one or similar:

Here are a couple I googled:

Interesting, they all look cheap. They remind me of the old liquid filled compases that folks use to stick on their dashes.

 

Another option is a temperature sensor that generates an RDS-EON FM radio signal. You can hook it up to the FM antenna of your head-unit, dial-in a FM frequency and then it shows the temperature on your radio display.

Here's an example (sorry, it's in Dutch but you'll get the idea):
