All, I just contacted Calibred Customs who did a lot of model X installation work. They are coming in April 16th to 22nd to NY/NJ area. They did a lot of good work for Model X blackvue installation 2 channel or 4 channel. There are many thread in the forum talking about their professional work. If some of you interest, we may able to get some discount from them if we have a group show up for installation.
