My Honda dealer back when I had crummy credit "included" a gps but it was never explained why and I tried to say I wasn't really interested. Somehow I ended up agreeing, likely due to some interest rate bait and switch as referenced elsewhere.

They couldn't "install" it there so I drove off the lot. They started calling the next week to schedule the installation and I wasn't very eager to go quickly. It became apparent they really wanted this installed and eventually bothered me enough that I acquiesced.

This brought no gps functionality to the car itself so I quickly realized this was because I had ~ 610 FICO and they expected to repo the thing at some point.

I paid it off but never bothered to remove it and the whole thing really bugged me. Nobody mentioned anything the last time I bought a car with an 800+ FICO so this is either for bad credit buyers or they just do it without asking now.
