I just replaced my (working) 5 year old F770 front + rear dashcam with a new U1000 Dashcam on my 2008 Jeep Commander.
The installation went smoothly and the new cam works great!
The included polarizing filter is a nice feature for the dashcam.
I have recorded several accidents over the years (including one where I was rear-ended) and nothing beats a video of the accident!
I highly recommend the U1000 Thinkware Dashcam because of the quality and reliability of this product.
