    Here you go, GaryMx. FYI, the 3M Dual Lock has been holding up well through the FL summer heat. A tiny bit of droop, but nothing terrible yet.

    Thanks, that*s really great. It looks like you have it wired right into the mirror/sensor harness, and didn*t have to run it all the way around the windshield trim, correct?

    Nope! One of the two wires you see in the pics is for the rear cam (runs through the headliner) and the other is the power, which I ran under the front edge of the liner to the A pillar and down behind and into the driver's footwell area.

    Correction from original response: I used a product (Snap N Go) made specifically for Blackvue cams which plugs into the front unit's power outlet, and then the business end plugs into the OBD2 port. That end has a switch, one setting for auto power off I think 4 minutes after when car turns off, or then a parking mode app which keeps power on until the unit senses a drop in car battery power too far below 12v.

    A lot easier to get the rear cable installed this time, partially from experience but also there just seemed to be more room to get my wire fishing tool through on the driver's side. Wanted to avoid any potential crossing-over with the curtain airbags.

    If you do decide to mount on the sensor cover, just remember to do a test live view before you permanently mount it to ensure it is unobstructed. I had to mount it a bit lower than preferred to keep the sensor cover and the black grid printed on the windshield mostly out of the field of view. I also had to do some surgery on my windshield solar cover to allow the cam to "see" when I use parking mode.

    Oh, and while I don't remember who it was, honors go to those who installed cams before me and who posted great instructions and photos on here for the first gen.

It lasted all of one week before I came out to find my camera hanging by the cable. And yes, I clean the hell out of the glass with alcohol before mounting it. Very frustrating! I guess my last ditch effort will be to try the EZ velcro strips someone else recommended. It's worth a shot.

    You should clean glass with acetone. alcohol leaves a residue which can hinder adhesion. Regarding double-sided adhesive tapes, I prefer 3M VHB - really aggressive, but only if the surface to which it is adhering is clean!

    Acetone might damage any paint/plastic dots/film on the windshield. If there are any chips that were repaired with adhesive, acetone will attack it. I would not recommend.

    Ditto to the 3M VHB. It's actually meant to replace welding in assembly line and it's what GoPro uses for their mounts that are attached to the outside of cars and planes.
