v1 performs slightly better with X and K bands, but the bel has a laser shifter that diverts lasers. also the v1 is notorious for false positives. i can program them on rx75....and, the whole system is totally hidden. i dont want anything on my dash, on my windshield, in my lighter, etc. the difference in detection is really negligble when traveling 80mph, and i'd have an advantage with lasers.

was also looking for a real pro installer...i have a brand new e70 and i wouldnt let the high school kids in circuit city touch it...this is not the easiest install. thx for the reply
