Just for giggles, called my dealer and one closer to ask about this. My dealer parts didn't know the 2013 maps were out, and insisted the only way to get the update was through programming upload via service. Service department insisted only way to do updates was via DVD bought through parts. When I told them they were giving mixed messages, they suggested I visit bmw.com and find some random software update site.....clearly don't know what they're doing. I fear for those trying to get upgrades there.
I called local dealer #2, they sell the same package for same price as offered at Tischer - they'll give USB for same price to do the upgrade yourself, or have you bring vehicle in and they'll do the programming upgrade for same $235.. Given they're close, I ordered and will just pick up the USB stick and let it run while I drive home.....
