This afternoon while enjoying the weather we decided to go ahead and install our tire sensors. I bought these over 3 years ago and never got them to work. We tried and tried. We got so frustrated and each time we just put them back in the box and forgot about them for 3-4 months. Well we finally sent them back to the factory and they said that the batteries were all bad in them. It was going to cost $200 to replace ten of the sensors (you can't replace the batteries on this model) so Doug just upgraded to the new 510 model that has come out that you can replace the batteries.
You can put the monitor on a stand or mount it on the windshield.
