Not really the same thing but, GM offers Cell phone app thru the free 5 yr On-Star deal that tells you air-pressure for each tire, as well as other info. We use it and it is exactly one pound lower than my digital gauge on both of our cars. I can live with it. But I still check the tires regularly with the gauge, but it has never been off by more than the one pound, so it this deal works as well it would be OK. I use a system I bought several years ago on my bike from a vendor in Daytona who was selling GW stuff. I can not remember the brand, screw on valve caps which have 2032 batteries and a little fob that gives readings. It also is dependable and has never faultered in the 5+ years I have had it. I check it out of habit everytime we stop as I am storing my gloves. Seems OK to me.
