I have given up on my TRX-2. Last Christmas I got it, and within four months, it stopped turning on. By chance I hooked up the USB cord, and it powered on. I thought it was fixed, until I unplugged the USB, and found out it would not turn on now without it. I researched the problem with Whistler to be told to send money, then they would figure out what was wrong with it.
Recently the firmware updates came out, and I brought it in the house to do that. I figured while it was in the house, I would update the programming as well. I put my old WS-1065 in the vehicle so I still could listen. It was like night and day. It had the same program in it but was constantly picking stuff up in my 40 minute commute. With the TRX-2 it would only lock on something every once in a while. I updated to have a better scanner, but the new one is worst. Oh well.
