So I just finished installing the Alpine ktp-445u behind the dash of my 2017 f150. I double checked everything and it looks to be right. After turning the truck off and back on none of the stereo settings hold. I change over to Sirius and it attempts to do an update but never does and it just goes away. Once I turn the truck back on the settings default back to an AM station. The clock settings stay the same. Also now the tire pressure just shows 3 dashes. Any help on all this would be appreciated.

 

You might want to check the wiring and the fuses. Sounds like something has been crossed.

 

Sounds like it's not holding memory for some reason. When I did mine I paid Crutchfield for the wire diagram and tech support because I had 1day. They are a wealth of knowledge. These new vehicles can make a simple task a painin the ***.

 

I checked the all wires again and it looks like everything is correct according to the color code that I followed. I will check again tomorrow when it is light out. I didn’t mess with any fuses but I will double check in the morning.

 

If you got one the FOR-CK11 wiring harness, some of them have mislabeled wires.

 

I did not use the ck11 harness.
