Hello, I've been a previous owner of a Audi A4 B5 which I unfortunately wrecked a few years ago. The experience was great however, so I decided to get a Audi again. I like the limo look and am not into short compact cars (there are exceptions though), that's why I decided that my new car is going to be a 2014 Audi A3 Limo. I found a decently priced listing at a car dealership, but the customer support could not help me out too much regarding the equipment. This is why I am asking here, whether a SD card slot is considered basic or additional equipment? The customer support of the dealership could only say "it should have a SD card slot". As I know that USB ports are optional, it is important to me that there is a way for me to input my multimedia, as I do not want to stream through bluetooth or use AUX. I've seen plenty of different variations of the media center that is located in the glove compartment. Some have 2 sd slots, a sim card slot and a dvd drive. some do not have a sim slot, some don't have sd card slots, some just have a basic CD drive etc. I understand the sim card slot is optional with the audi connect upgrade, which I don't need. If software updates for additional features are possible, I wouldn't need a dedicated sim slot as I could tether from my phone if I wanted to use google maps, stream radio etc.
