I did some searching for S100 software updates and came across skins made by KoTiX Design. I vaguely remembered information about these being mentioned in the aftermarket nav thread. I installed updated firmware and the kotix skins last week. I like the Kotix carplay skin a lot. The skin upgrade comes with Mirrorlink, which allows you to look at your android phone and control it directly from the S100. See http://kotixworld.blogspot.com/2016/...irrorlink.html. It also comes with an alternate audio player. I changed from the stock audio player to the nitrogen player and am amazed by the better response time accessing the sd card and usb card for songs. I use a 128 GB usb stick. The extremely slow mp3 file access was my biggest complaint about the S100, and it is resolved! Overall the unit seems faster when booting and moving around screens.

At $28 for two skins this was a nice upgrade. I highly recommend it. After the fact I also came across the Audizine Telematics Forum, which has a S100 firmware Update DIY thread that tells you how to do all this.
