This was a upgrade to the C5 that I had installed. I did not think that it could be improved on but it was. The K2 with two cameras was easy to fit all be it a bit tight to get it all in under the seat but it did fit. The bulkiest part was the excess wire but it did all go in beside the rear suspension spring. I have tried it on a run but as yet not downloaded the video . The product is the best on the market as far as I can tell and would not hesitate to recommend any product by Innovv.
