My question is how much of a warning time does a battery operated unit provide compared to a cord unit?
UPDATE: I just realized you may have been trying to view the old video, which also played for me. We have a newer video that provides a close-up look at the XTR-540 in action. Also, it is in HD so it will require some bandwidth. As for the XTR-540 itself, we don't have hard numbers but we estimate the warning time for a battery operated radar detector such as the XTR-540 to be about 20% less than a corded model. There is a bit of a trade-off for the convenience of having a cordless model. Of course, the performance will not be as great as a more expensive, higher end radar detector with all the bells and whistles. However, there are a number of vehicles out there today with dashes that are not designed to accommodate corded radar detectors, and as cordless models go, The XTR-540 performs well, which makes it a good choice for situations in which using a corded radar detector is awkward or just isn't feasible.
