If you look back 8 days in this sub there’s a thread called dash cam. I posted my setup in that thread.
I’ll repost it here.
I'll provide Amazon links for clarity but, I have no affiliation with any of these products. I wanted a dash cam with front and rear cameras and after some research decided the VIOFO A129 Plus Duo was the best affordable dash cam. Also this. I decided to mount it on the passengers side so I could mount it higher on the windshield and it wouldn't interfere with the rearview. Photo. You can then very easily tuck the power cables along the headliner and down the A pillar photo. Then run the cable up under the dash. Just the open area above the pedals. Essentially you just feed it over some of the wires and brackets that are up there. Maybe use a zip tie or 2. Then you can plug it right into the USB port at the front of the console. I did that for a while, but after a hit and run I wanted one that stayed on. At first I was going to go the traditional fuse tap route but it's not possible on they CX-30 due to there not being enough space for the tap with the fuse box cover on. Realizing the cig lighter accessory plug inside the console is always on I found this RHUNDO It monitors the battery so you can set it to auto turn off if the battery gets down to a certain voltage. Also set a timer, 2, 4, 8, 12 hours after vehicle is turned off. To use that I ran/tucked the power cable under the console and then ran it up the side and into the console photo. I also had already purchased a console organizer that made this even easier. photo Under the organizer photo. This set up won't be for everyone, but it's worked great for me. Hope this helped. Also the rear camera was very easy to install also. Just ran the power cable up under the headliner the whole way back. No extension needed.
