The one in the video is an older model, we've stopped those ones, and now only do the ones with the dial down below, main reasoning behind this, wasn't the dial, but actually relating to the heated windscreen options, which the one in the video lacked, but the one on the website does contain, but as a general idea this video is still up

You may need to leave the original button panel plugged in, but hidden away for this to be resolved, but we've only had to do this in cases where we've installed a replacement head unit, not an LCD panel, which are as plug and play as it gets, I'm not too familiar with Webasto in all honesty, so I couldn't advise specifically on this function

@@iceboxauto How to connect these panels both the same time?

may be I should to change any options in hidden settings?

for example item in the list of options "Barring rev" what does it mean?

Possibly, it would be hard to diagnose over the phone, so I would suggest if you can send us an order number so we can see which unit it is you've got exactly and send us a short video of how the unit is freezing in the car, and I can help from there, our email is admin@iceboxauto.com

Thanks, I have sent you an email. I will appreciate if you have a contact number I can call.
