Installing ACC in a Mercedes GLB

[Rax011]

Can I install ACC on a 2020 Mercedes GLB with cruise control? The car has a front radar.

Yes, it's a pretty simple process, you just need to change the left buttons on the steering wheel and code EZS and FCW, then do the adaptation to recalibrate using XENTRY.

Is it possible to work with XENTRY offline?

Yes, the adaptation for recalibration will be done offline and you will have to drive around a bit during the process with your laptop in the car.

I've never calibrated before! Can you explain it somehow? Make a guide, pictures, or something?

Install XENTRY in your language and follow the instructions... it's very simple.

Do I need to do all the actions in the FCW module?

First, you need to install a new panel with Distronic button. After that, you need to code and calibrate the radar.
Here are all the stages and ECUs you need to work with.

It is extremely important to back up your configuration before making any changes.
