They work, Waze just doesn't show on the small screen with your Speedo (instrument cluster) im using 19101. Before 3.4 both Google maps and waze didn't show. On 3.4 Google does but Waze still doesn't.
If you have a compatible car it should work after updating to 3.4
Yes I wish they did
depends on what size storage you have. since you are NA i doubt it.
not sure what you mean by "not on the homescreen" it won't be on the home screen it will be the same as usual with the added benefit of showing google maps directions on the small screen
Do a master reset this will fix it.
find the relevant file from the file archive and create a matching autoinstall.lst
Not really, 19101 can have auto dim turned off it's not a option on newer versions it's forced on
