I purchased a Dash Cam but, as a convertible owner, I wanted professional installation to ensure that (1) the wiring was placed behind the header properly and (2) that the power connections worked without extra unexplained power draws.
The result was worth it! It looks awesome and works flawlessly! Thanks to Chris for all his help!
For those interested in getting a Dash Cam for their convertible, I would recommend Nextbase 522. It has an available Cabin View optional attachment. The main unit attaches via magnet to the window ~ beautiful and elegant! It's easy to mark a scene (touch screen and/or button). The app connects seamlessly between the 522 and my iPhone so that I can (frequently) send myself brief videos of my travel (for Facebook); of course, actual crash incidents are easy, too!
