Hi D3ggy, yes all the steering wheel controls and Siri works. I also tried Waze, Google Maps and Spoitify, they all worked fine. I have just done the OTA update for the 2021.02.02 firmware and it seems to be fine as well The 2021.01.28 was a little buggy for me where sometimes it doesn't show my paired phones at start up, like my phones are not showing up on the "auto connect" screen. I have to unplug and replug to get it working again. Hopefully the 02.02 firmware will be better.
I took a gamble before your reply and installed 30.01 and it works. Think I may stick with this one. For a while, it seems to connect fast and works.
