Passport 8500 X50 has saved my *** more times then i can count. Range on the thing is fricken amazing just be sure to mount it high in the center of the windshield for max range. I know lots of ppl like to have them low on the dash but with the X50 you cut it's range in half doing that. I leave it on highway setting no matter where i go since that gives it the longest range. Think it's 300 bucks if i remember correctly.
