Mr UPS man just dropped off my detector. Firmware is 4.5. I went into the programming and found KU, SWS, and POP turned off. I turned on POP and left the other two off. I switched to fast power on. Left everything else at the default settings for now. I am curious about the USA vs INTL setting. Reading other posts there seemed to be some concern about the unit possibly not reading far enough outside of the designated frequency that the detector might miss out of tune radars. Anybody know if this has been put to bed yet? Any other reason why I might want to leave it in INTL? Any other programming advice? Now that I have the unit and moved it around in the car I have decided to use a mirror mount shown here ------> http://t-rexsoftware.com/greatlakes/corvette.htm Im hardwiring with an invisacord ------> http://www.invisicord.com/ I just got done ordering these pieces so a report will follow whenever they show up.
