I could not wait to get home after work today and pick up my RX from the mail! The shipping was fast, I ordered it on Wednesday. On the way home my 8500x50 started another self cal test, but it still alerts to all bands (except laser) in plenty of time. I can't wait to program my RX and start testing it out. According to the Beltronics web site, here in Texas (Austin) we have over 189 confirmed speed traps making us number 2 in the country. Houston, which I travel to a lot is number 1, so I have plenty of oppotunities to find out if I wasted my money or not. I placed my x50 high by the rvm with X and POP off, and on Expert mode. Any suggestions for settings and unit placement for my RX from you guys will be greatly appriciated!
