FAQ
Is it permanent? Yes, one payment.
Is this a real power increase? Yes. It’s BMW’s own CS engine calibration, the same software the M3 and M4 CS left the factory with.
Why is manual different? BMW never built an auto spec CS with a manual. Manual cars get BMW’s dedicated manual CS calibration instead.
Does my software version matter? No. It works on every G8X version.
Will a dealer update undo it? A dealer software update can overwrite it. Let us know and we’ll sort it.
Will it affect my warranty? It’s genuine BMW software, but any software change can be questioned on a warranty claim. Check yours if it’s still covered.
Pick a time for your technician session, then you'll go straight to checkout to lock it in.

LOYAL BMW ENTHUSIASTS
Had the NBT EVO ID4 to ID6 upgrade done on my 2016 M4 and the difference is huge. The new iDrive interface looks much more modern and having full-screen Apple CarPlay makes the interior feel years newer. Process was smooth and everything worked perfectly.
My X1 came with the newer EntryNav2 system but didn't have Apple CarPlay activated from factory. Bimmer Drive enabled it remotely and now CarPlay works wirelessly exactly like OEM. Very easy process just connected the ENET cable and they handled the rest.
My G30 5 Series already had factory Apple CarPlay but it was stuck in the smaller split-screen layout. The fullscreen activation made such a big difference. Looks cleaner and uses the whole display like newer BMWs. No aftermarket hardware needed.
I was looking at aftermarket CarPlay screens for my F30 but decided to keep the factory system instead. The NBT EVO CarPlay activation gave me everything I wanted while keeping the original BMW interface, steering wheel controls and sound quality.
Got CarPlay and Android Auto activated on my G20 3 Series. The whole process took around 15 minutes and now everything works exactly like it should from factory. Great service and saved me a trip to BMW.
