I'm asking myself the same question and no one can tell me...
I know it's an antenna connector, but I don't know which one.
Is it the satellite radio antenna? :oops:
Did you connect the climate controls?
I tried without the controls and the radio didn't work.
After connecting the climate control it worked.
I used the codes that are at the beginning of the post.
After programming, everything seems to work fine! Even the camera!
Now we have to put everything together and find the maps for the GPS.
Is it necessary to put an antenna on the GPS?
I'm understanding more with this diagram than with the first one...
In the first one it is not very clear what goes to the truck connector and what goes to the radio connector.
Tomorrow I will do the cable
