Hello everybody. I have a 2015 Mini Copper Base and I want to upgrade the NBT radio. I have a local offer for the Visual Boost 6.5" Radio, controller, and the Screen for $300 but I was wondering what else I would need to upgrade the radio from the NBT to the 6.5" Visual Boost Radio. I would love to go to the 8.8" with everything but 2K is currently not anywhere near what I can afford so going for my 2nd best option. If that is not a good option, I was also looking at the Android one from SCP Automotive. Please let me know what you think or if you have any advice.

SCP Auto Radio - MINI F-Series Android Display Upgrade - Android Auto and Apple CarPlay (scpautomotive.co.uk)

Thanks!
