Care to elaborate number 3?1. Better filtering for Acura, Honda, GM, Cadillac and Chrysler Pacificas, Mazda，Toyota
2. Can turn off the power supply, start the car will not automatically open;
3. High voltage protection to avoid trucks burning radar detectors;
4. Like R7, the detection range of K-band is extended to 23.95.
5. Custom voice;
That's what I figured too, but I might as well put it out there.. Since I don't plan on getting the R7. But if they came out with a hardware revision of the R3 with the changes, I'd pick up a 2nd R3.Highly doubt any of those hardware related requests will happen...
