JB1 VS JB4

I just picked up a new 2020 C43 last weekend after turning in my 2017. I had the JB1 on the '17 before the JB4 was released and never upgraded. I'm wondering if the JB1 is still compatible with the newer models. Is anyone running a JB1 on a '19 or '20 C43?

We no longer offer it, JB4 only, and for the FaceLift models you'll want that BCM for maximum performance too!
