Yukon has a rubber gasket that allows water in and no escape. They built it that way. It's on purpose

I have a similar problem in my 2015 escalade I live in California and the gps stayed on michigan could it be the antena...

Mine is showing that I’m in the middle of the ocean you think is the antenna?

i have a 2015 Suburban, and mine has been replaced 3 times so far, going for a 4th now. 122,000 miles.

You are the best I have lincoln mkt 2018 problem solved thanks GPS system in car antenna

So is that what happened to ours we live in central Michigan and says we are on Wisconsin.

hey guys i have the same issue with my 2015 silverado but the difference was that mine XM still working fine so I replaced the antenna and still is doing the same thing with the new antenna GPS and onstar still not working but XM is good. any ideas on this

Won't this just be a reoccurring issue after replacement?

I think I have this issue on my '14 Sierra 1500. I can still place OnStar calls but have no XM or GPS signal.

Did you say warranty covers this problem?

Any idea how long that antenna would be under warranty for??

My navigation is just showing a compass and nothing else

Having mine replaced today, no charge... mine was saying I was in the middle of no where..

Any idea on where to buy a new anthena thanks

Do a sensor on gmc causes your GPS not to work

Not exactly something you can do a quick software update to fix.

I'm in the Atlantic Ocean right now but I was in the arctic Ocean just days ago

Actually, the GPS antenna is the square brick mounted on the PCB.
