Today I finally took the leap and installed the Blackvue DR750S-2CH in my Model S. The installation took @ 3 hours. Most of it was running the cable through the rear boot and into the trunk ( I wanted the installation to look as professional as possible). I must say it was well worth it. I will have the same camera professionally installed in my Wife's Model X (I'm not as confident that I can perform the installation considering the windshield). I'd like to thank @K-MTG for bringing this to my attention. I was ready to pull the trigger on the DR650S-2CH before I saw his post regarding the new model. BTW I purchased the DR750S-2CH w/ 128GB SD for $415 shipped from hdvideodepot.com (authorized reseller). You can use code "SUBCOUP5" to take 5 percent off.
