I was wondering if its possible to swap out the '99 STS radio and drop in a stock Cadillac NAV system. Not sure where I can find one either, but if it is possible anyone know where I could in fact get one? I've used the blue search button and really didn't find much other than people installing aftermarket headunits.
Found a thread on it but its all about '02+ models, nothing about my '99. And it sounds like it never worked, anyone actually get it to work? Just an idea that I had, thought it would be nice, but if its not worth the trouble I am probably just gonna throw this out the window.
You'll get a far better system with better maps and GPS performance, easier to update, if you stick a Garmin 205W on the windshield. Not as bling, but anything is better than a 10 year old GM NAV. Even a paper map is better.
