I purchased this one, it works really well and the front facing camera is super clear, the rear I wish had a higher resolution but it gets the job done and records simultaneously.

I love it. BUT it clips over your old one and I had to jam a sponge between the mirrors so it could be angled correctly.

The clearance for a new mirror on challengers is very small.
