I have an appointment next Monday with McKenna BMW for them to take a look at my comfort access system. I had my tint done at STM, and after delaying several times over the last few months, I'm finally taking it in to check out. Hopefully it's just my CA system and not the tint, but putting the comfort access problems aside, STM did a fantastic job on my install.
I will step up and warn you that Huper can potentially interfere with your comfort access system. I've done a ton of research on the subject since my CA problem started after the install. I'll be updating my thread in about 2 weeks after I get my car serviced.
