I recently installed my STi-R plus. I was on a long drive and thought that I would go into setup for the first time. I could remember the buttons to hold, so I held down 2 (I think the 2 on the left) for a few seconds. The displays said something like "receiver off". I tried it again and nothing happened. Indeed, now my radar receiver no longer detects anything, ever. I did figure out how to enter settings, but I can't figure out how to get the radar to work again. I even did a factory reset. The GPS based alerts (speed trap, etc) still work, but nothing from the radar receiver. Do you guys have any advice?
