I have K40 calibre. Front and rear radar detection. To the best of my knowledge, it is the only stealth built in that has front and rear radar. No?
The rear detection is a must for me. Saved me many times.
V1 has it, but is not a built in. 9500 built in does not.
K40 has its issues, sure, but it is the only dual radar game in town. Unless something new is out?
