1. Your PN was for the original one. I thought it was only for the 50, but it seems it was for both. However, they are only for 2010s and lower. The 50i had it as a factory option at one point.
2. The new one. Due out later this year. Works on the 2011+ 35 and 50. There was a news release at some point about it.
