I know it's been awhile since your retrofit. Can you provide status on how its gone? I connected with BimmerTech and they communicated that in order to add the 6NR to my car, I'd loose my BMW Assist...which is my concierge service. Did you loose functionality in order to gain the ability to play videos, apps, from the Combox? That's a tough choice!
