This was done awhile ago for our customers dads car. We are very honored that she trust us enough that we have installed dashcams for 2 of her cars, her sisters car and now her dads car, this Honda Accord.
The Akeeyo AKY-D9 is an excellent choice for dashcams as it provides excellent video quality even at night. With the option of running full 4K for the front or QHD front + FHD rear, you have a choice in video quality depending on your needs. We also installed the hardwire kit, so parking mode is enabled.
Overall, installation for this car is pretty simple. You can definitely DIY this provided you have multimeter which is needed when searching for fuse locations to tap.
