so i got a call from my local retailer that my new X50 has came in. went to pick it up and hardwired it right away. it works just fine and love it. then i checked the REV. and it says REV 5? i mean, they just got it from escort. and also i noticed the box it has a little white sticker on top to cover-up the fcc id "QKLX5M4" (i can see through the sticker) which is supposed to be the REV 6.1. are they switching back to REV 5? or they still make em maybe?
