IOS to IOT

ldurmon · May 7, 2023

I have a 2022 TrailBoss with the 6.2l and it has the IOS radio. The dealer told me it would do the trailer TPMS but obviously it does not. Purchased used and my previous TrailBoss did have advanced trailering and I really miss it. Can I have the IOS changed out and add the TPMS reciever to get the advanced trailering package working? I know it would involve reflashing. There is lots of knowledge here and thanks in advance for the help.

IOS and IOT both were able to option the advance trailering system. Difference between IOS and IOT is IOT is embedded navigation.

GM has no way to add U1D advance trailering, nor does it seem the aftermarket does either.

ok but is there a way to get the TTPMS without advanced trailering? The TTPMS is what I really want in the truck. I have the old sensors from my last truck that I want to use.

Have you tried the change TPMS sensors. The vehicle TPMS sensors for the 2022 trucks (refresh that is) are different than the previous year. I am assuming the trailer TPMS sensors have also switch to the 433 hz ones.

No. Need advance trailering as it has the applications in the software to run the trailer TPMS.

The truck is not a refresh model. I am picking it up today and will look for the receiver behind the license plate when I get it. Purchased used with only 13,000 miles on it. Has everything I want except advanced trailering. The dealer told me the trailer tire pressure would work with it but from what i have seen looking up rpo codes he don't know what he is talking about. Will add it if possible. Thanks so much.
