bcohen2010 - FoDaddy pretty much summed up my motivation for wanting to make the switch.
The only downside I can see with an aftermarket head unit with a 6" to 7" screen, is that it will be a target for theft. My perception is that aftermarket units are desired by thieves, but stock units are not.
I have installed aftermarket head units in other cars to gain Bluetooth (access to streaming services and playing files from the phone) and also hands-free calling functionality, but in those cases I opted for single DIN size units that have buttons and LCD displays. They look primitive compared to today’s touchscreen units. Maybe it is a false sense of security, but I feel thieves would not be interested in those types of stereos.
Anyway, driver assistant tools like Apple Car Play and Android Auto require a touchscreen in the head unit, so if I go that route, I am going have to be smart about where the car is parked, and hope for the best. The car does not have a security system, and I will not be adding one.
I guess a low tech anti-theft solution like this could be an option, too.
