I have purchased a V1 last week, ordered it on 3/24. I have posted the firmware version earlier here http://www.radardetector.net/What-so...ur-V1-657t.php
Upon further checking out the unit I noticed that there is a new programming feature after the J feature, which is “u”. By default the arrow ahead is on when I change it to the arrow behind and switch the unit off, and back on it says “E u r” and of course P o P. Instead of A mode it now has 2 different modes a big U and small u. There was no mention of this in the manual, so I don’t know what these modes are for. I thought I would let everyone in this forum know.
