Big ups to Vic of Mobile Masters. I recently purchased the Blackvue DR750S 2-CH dash cam for installation (hardwired) in my MB E-Class. Like most folks I called around and was told by one car audio install shop that I could expect to pay $300+ as it was a 3-5 hour install! Vic did the job for about 1/2 the cost and it maybe took him 90 minutes for a complete clean install. You make an appointment...they come to you...it really doesn't get much better than that. Thanks again!!!
