Question K40 false alarms help please

Greetings,
I saw the recent thread on radar detectors with many championing the K40.
Well, the CLS55 that i bought has the K40 2000 with laser difusers non-bluetooth version already installed. (i don't know where it was installed but could try to find out from the M-B dealer.) i find that they have so many false alarms to make using it almost worthless. it has never failed to pick up radar but there must be 100 false alerts for every real one. it is chirping almost all the time! i keep it in city mode even on the highway with still very frequent false alerts and have to turn it off completely in the city. i have called K40 and they say my unit has the same detectability as the current calibre version but doesnt have the installation ease of this blue tooth version.
i have had older escorts and bels that never falsed like this.
any advice would be appreciated!

take it to you local dealer (K-40) and pay them to diagnose the problem, turn it off and get an older bell/escort (I can imagine what a more sensitive unit would be doing ) take some photos of the whole install and post them here...

good luck

Belive it or not, alot of city false alarms come from the automatic door opener in stores, such as markets, drug stores, etc.

BTW.. Don't speed on city streets--reserve it for the highways and be responsible racers.

Drove me crazy

Had K-40 {hidden installation} in my M5......
So many false alarms that I turned it off and never used it again ....
Couldn't stand the alarm going off all over the place ...
Won't buy a K-40 again!

I do believe it and I am aware of the door openers setting the false alarms ..... BTW...How does racing on the highways make it more responsible than city streets If you want to be responsible racers race on a closed circuit track or at your local 1/4 mile track

Why have a radar unit if you don't race (or speed) on the public ways?

What I meant is that if you have a need for speed it is safer on the highway due to the nature of it construction with no cross traffic or pedestrians. How can anyone disagree?
