Merry Christmas and Happy New Year!

New to these forums. Working on keeping a 1999 GMC k1500 Suburban going. Great vehicle, just tired. Just got a new engine, next is redoing the rear axle and suspension, and then the interior.

 

I have a 2019 Tahoe with Nav but I don't want to sign up tp OnStar to use it, is this possible/ OnStar lady say no but come on really.
