We picked up a 2015 Passat TSI Limited back in January. I'm somewhat confused.... the owners manual shows heated mirrors which are turned on with the power mirror switch... this is not a feature on my car. The manual talks about the compass feature on the display, another feature that's not on my car. I wanted to upgrade the Premium VIII Audio, dealer said can't upgrade, that vehicle icannot be upgraded with a better Passat audio system having a navigation system, satellite, bluetooth like the RNS 315 or RNS 510. I blew a fuse, can't find a fuse diagram in the manual or online, dealer said it's not available. I was reading about programming the key fob using the menu icon on the steering wheel, not there. I'm beginning to think that "Limited" means limited features. Can anyone clue me in what I'm looking at here? What exactly is a TSI Limited model? Thanks for your help.
