So, I bought a refurbished RX65 from the Escort Ebay store. When I received the unit, I noticed that the manual had an extra piece of paper in it that says, "This model does not have TSR as referenced on page 2 and 22." Is TSR that important? It's anti-falsing software. Anyhow, I was considering sending it back, but if it's not that important, then I'll keep it.
Can I still update the firmware on the refurbished radar detector? Someone let me know a little more about what I'm missing.
