I test drove most of these before buying my 15 CX-5. The only one that came close in my choice was the Honda, but the Mazda looked soooooooo much better.

The remaining adhesive is tough to get off, but I find a little heat and mineral spirits works best. Then Meguires 105 cutting compound on a pad on my drill returns it to a new finish.
I changed my oil this week and installed a Fumoto drain valve for the oil plug. Now, to drain the oil, I just slide the lever over and close it when it's drained.

I did mine yesterday on my 2015. I was able to remove and then reinstall the nylon connector without cutting it. It was not easy, but doable. You have to twist the connector on the trim side to pop it out, then reverse to reinstall. Good luck!
I just hard wired a Garmin GPS and Escort radar detector. Thanks to Seminole for the "how to". I have 2015 CX-5 and I had to install the 'add a fuse' with the fuse facing up (the red wire going out to the left) for it to work. ???
I also replaced the 15 amp fuse that came with the kit with a 7.5.
