whats up guys, new to BMW world. just picked up a 2013 bmw x5m. love the truck so far. Im looking to replace the combox so i cant connect my iphone app to the car and also i hear there are some new features etc. current combox i was told is 2g and new one is 4g. just looking to see if anyone knows for sure what the the upgrade will be. like will it bring new updated map, more functions,more lively ( kinda like the new bmws) display and stuff, apple car play etc?? has anyone done it before?? also some input about the car would be great. things to look out for what goes bad etc? thanks
