Somewhere in-between Bruce, which I'm sure you are making every effort to do.I do find it a bit confusing. On the one hand people think I should let her be responsible for herself and stew in her own juices and on the other I shouldn't let her make what most of us think is not the best financial decision regarding a car.
As far as the nav system, yes, you can buy an aftermarket system that will show on the OEM display but not one that is plugNplay. You would have to find someone that can sync the new software to the OEM software/hardware and it will usually be someone that has to hack into the OEM system. It's not the fault of the aftermarket people...it's because the car manufacturers and their own vendors insist on using proprietary software and hardware. They don't WANT anyone else's software working on their hardware and there is probably a legalese blurb regarding that in your owner's manual.It is really unfortunate that you can't buy an aftermarket Nav system that could show on the built in 7.3" display.
What GB said!Somewhere in-between Bruce, which I'm sure you are making every effort to do.
Yeah I get that, don't have to compete if you don't let them use your hardware. There is definitely a "on one hand verses the other" functionality discussion with regard to the built in system and a portable one.They don't WANT anyone else's software working on their hardware and there is probably a legalese blurb regarding that in your owner's manual.
