Steelmate TPMS-85 Bluetooth TPMS System
 

For anyone looking for a TPMS solution. Pretty happy with this for $125. Simple and works well. Had a few of my wheel weights fall off while washing the X5 so figured I might as well take advantage of having to re-mount and balance my tires. $120 to install. Going to pick one up more my Z as well.

Only gripe is it won't connect to my Eonon unit for some odd reason (connects to my phones every time).
