Thinkware F200 Pro. I found it on Best Buy's website with $50 off a couple weeks ago so I thought it was a decent deal. Apparently it's the same one as GM sells. You could just buy it from GM and have a dealership install it... it's not a very good deal though. --------------- Here's my route-over-headliner instructions! My car is a 2021 Bolt Premier. DISCLAIMER: I'm not the most handy person, so take my instructions with a grain of salt. Variations of these will probably work. I used the following: Fish tape for feeding over the headliner (my fish tape is smooth and thin wire... it only bends in one direction). Scotch tape. Fishing line (I used 40 lb test, not that it matters). May be optional! Moderately-sized (but not tiny or large!) cable ties. A small piece of thin/long plastic (I used the handle of a tiny measuring cup from the kitchen). First, open the hatch of the Bolt. You should see some rubber weather stripping along the edges, 2 rubber wire coverings between the hatch and body of the car, and a long plastic interior panel toward the top. Carefully pull one of the wire coverings off on both ends (I did left covering) on both ends. NOTE: Pulling them off and putting them back on is the very hardest part of these instructions! Here's the rubber coverings pulled off and a glimpse the headliner below the weather strip: Hood Grille Blue Automotive lighting Bumper Now, below the inner-most weather strip is the headliner (roof) fabric. You can stick your finger in there (try it!). Tape the front-end of the rear dash cam wire onto the fish tape tip. Making sure there is no cabin lights in your way, wedge the fish tape in between the weather strip and headliner and push the fish tape until it reaches the headliner edge at the windshield. You may have to try a few times if you feel resistance (doesn't seem to be a big deal). And here's the fish tape from the rear: Hood Motor vehicle Blue Automotive exterior Trunk And fish tape tip at the windshield: Wood Font Paint Tints and shades Shade Pull the fish tape tip out of the headliner at the windshield and remove the scotch tape off of the cable. Now you can conceal it in similar ways to the hard wire kit to plug it into the front camera. BEFORE PULLING THE FISH TAPE OUT, tape the tip up again so it doesn't hook onto anything as you pull it out. Return to the hatch of the car and on the other end of the cable, tape a cable tie to the plug so that the tie acts like a rigid ribbon you can tug on. Wedge the cable tie ribbon between the weather strip and headliner closest to the rubber covering you pulled off. Maneuver the ribbon so that it goes through the hole of the rubber cable covering and pulled the cable through. NOTE: You may be able to get away with using a cable tie in the below! Try pulling the camera cable through rubber covering before doing the below. If that didn't work: Using ANOTHER CABLE TIE, tie a piece fishing to the bulky end of the cable tie (use something like a clinch knot used in fishing). Thread the cable tie ribbon through the rubber cover on one end and pull it through to get the fishing line through the rubber covering. On the camera cable, remove the taped cable tie and tie the fishing line below the cable's plug (again, use a good knot!). Pull the camera cable through the rubber covering by pulling the fishing line through. Take the cable tie you used for the fishing line and tape it back onto the cable so that the ribbon sticks out. You can stick your fingers between the plastic interior panel nearest rubber covering. Maneuver the ribbon through the hole in the hatch until your fingers can grab it within the interior plastic panel. Pull the camera plug through and give it a little slack. There you go, now you can plug it into your rear view camera. Woo! Here's the end result of pulling the cable through the rubber covering and panel (with cable tie attached). Hood Grille Motor vehicle Blue Automotive lighting At this point, you should have a bunch of slack cable hanging out of the car and sticking out of the headliner. Wind the cable up and put some twisty ties or tie wraps around it and then wedge it under the headliner. Setup the rear view camera and make sure you have enough slack cable before proceeding. Here's what that looks like Blue Hood Azure Motor vehicle Automotive design Returning back to the rubber covers. Using a thin and rigid piece of plastic, gently push 2 of the little grasps in the plastic mounts so that the plastic mounts come out of the holes. Put the rubber covering over the plastic mounts and make sure it's really tight. Plug the plastic mounts back into the holes. Do this for both top and bottom. Here's the little plastic cup handle I used: Cosmetics Finger Nail Thumb Nail polish And here's the plastic mount popped off by releasing two plastic grasps by pressing in with the plastic cup handle.

I need to order micro2 fuse taps... -------------------- I'm a newbie with the automotive electrical stuff. Our OP mentions the fuse taps he used are Micro 2. So how do you verify that will work in your Bolt? Well, the owner's manual doesn't tell you the fuse types used. But it does tell you where both fuse boxes are. And on the 2021 Bolt (and probably all Bolts), the instrument panel fuse box is in the cabin to the lower left of the driver. Mine has a little fuse/plug-looking icon at the bottom. The owners manual tells you to pull at the cover from the bottom. Just an FYI, there's an extra piece of plastic down there that seems like it's part of the cover, but it's not. Make sure you don't pull on that extra bit of plastic. Anyway, you give it a good tug (but not a tug that would break this plastic) and it comes right off. To put it back on, the owner's manual tells you to insert the top tabs first and then push it in... pretty easy. Now, on the back of the cover, there's a diagram and a legend by fuse type. For each fuse type, there's a list of fuse numbers. The most numerous of which is Micro 2! I think some dash cams with hardwire kit come with fuse taps. Mine came with a hardwire kit, but no fuse taps. So if you're in my situation... the name "fuse tap" doesn't seem to be a standard a name. If you search a mainstream auto parts website, you may not find anything for "fuse tap"! I've seen "fuse holder" and "add-a-circuit" used for these too. I found the company "Littelfuse" makes a "fuse tap" called "add-a-circuit"... and it makes one for each fuse size. I think I will order two Littelfuse 10A Micro 2 Add-a-circuit from Advance Auto Parts (because I hate Amazon). Owing to their simplicity, I can't imagine anyone can make bad fuse taps. No? If you know something about low quality fuse tap companies... please let me know!
