The two that we prefer is the K40 caliber dl/h with diffuser ex and the passport 9500ci the technology in the 9500 is a bit more advanced then the k40 and we prefer the cosmetics and control of the k40 to the 9500. Both great built in solutions we use everyday. The biggest thing these have over ANY of the dash mount units in protection against laser not just detection. Have a good afternoon. Happy Sunday!
