I didn't see the word "need" until after I asked the question. The original post about the option simply said they enabled it with FORScan, which is why I asked for clarification!
My only experience with CF was a license plate frame. the shiny finish delaminated in about 3 years. This was a ~$40.00 license plate frame!
Needless to say, I will be staying away from any exterior CF upgrades.
My office is above my garage. The only access to it is thru the garage. Everytime I go to/from my office, my Mustang GT wakes up as in a greeting and saying, "Let's go for a ride!". I talk back to her saying, "in a little while" or "Not today, it's raining" or something like that.
The VIOFO unit is designed to work off USB (5 volts DC). The Uniden R8 is probably designed to run off 12 volts DC. This is one reason why I' so focused on the VIOFO A229 Pro!
Are you saying the USB port on the rearview mirror is ALWAYS powered - even after you have turned the car off? If so, many people would say that is a plus! Great for monitoring your car while parked. Also a battery drainer. 🤬
