If we did do the swap I imagine we would both have to pay the dealer after that to program the new TPMS sensor ID's into the car's ECU. At least that is how it would have to be done with Subaru. I am unfamiliar with Mazda but I bet it is the same deal.
I'm pretty sure we don't have TPMS sensors. I think the ECU somehow uses the ABS sensors (etc.) to sense differences in wheel rotation speed to detect a problem.
And waves to a semi-neighbor, as I commute through Trenton, NJ every day... not far from Chester!
Thanks for the tip. I just priced out a GT with tech and a Touring with tech plus moonroof/Bose and Sirius. This makes both cars the same except for climate control, advanced key, leather, heated seats, 19's vs 17's. It's only a $1600. price difference which is about what the aftermarket leather & heaters would cost. I think I will get the bigest bang for the buck by going for the GT and trading out the 19's. Then there's also the consideration that at trade in time the GT will be worth a little more than the touring.I wanted GT+tech initially but ended up with Touring+tech+17" wheels but got the leather/heated seats as dealer install. I like it. I also think about the time when I'll need to replace the tires - 17" are more economical than 19". So it's really all about the climate controls
