I installed a VIOFO A129 Pro (HK3 ACC Hardwire kit) in our 22 Highlander a couple months ago and I am very happy with it. They sell multi-channel but I chose single channel only because I didn't want to deal with the second channel wiring. It is my second VIOFO dash cam, the first has been working fine in another vehicle for 5 years. Ordered it direct from the VIOFO site (China) on sale and free shipping less than $200, better pricing than Amz. It was delivered in a timely manner, although the site order tracking function was not functional. The site and communications read a little "translated" but I have no complaint with the product or service and they have been in business for many years.
We've had a pair of Viofo A119's in our two cars for years, but I very recently upgraded one of them to the Viofo A329 (front facing only). Quality is superb. They have a range of models to suit most applications (ie front & rear facing) and with different resolutions, etc. Check out their website
Learn more and you're sure to find a model which suits. I can't comment on prices though, as we always pay a premium down here...
