Hi,
Is any body else getting 'false' readings on the radar detectors for newer cars with collision avoidance systems?
I've read articles in magazines suggesting that it doesn't happen, but I get a lot of readings on the highway when close to newer BMW's and Audi's.
The 'proof' recently was when a comcast van parked in front of me as soon as his reverse lights went on the detector started chirping when they went out it stopped.
I have what I think is a K40 which was installed when I bought the vehicle it has worked well but I have no info on it ie age etc.

My detector picks up an Audi miles away. It has become more of an annoyance then a help.

Yes I've noticed the same with my passport detector. I get K band alerts. I could disable K band (as I have done with X band) but some law enforcement in my area still uses K band rather than Ka or laser.

I believe that is the blind spot detection systems that you are picking up.

I know new Cayenne owners with LCA have their detectors go nuts, but I believe the V1 has an upgrade that addresses this (don't know for sure as I don't get many false alarms, but I've read about people being happy after upgrading their unit).

The V1 does indeed have a firmware update that blocks false K-band alerts from traffic flow monitoring systems, which also seems to filter out most falses from other vehicles in my experience. I believe this update became available 1-2 years ago. I've had good results with it.

Laser alerts from Infinitis and others with front collision detection systems still come through however.

duplicate, sorry

I can pick up an old person in a caddy with lane-departure radar from a mile away.

Thankfully, most of the CHP I see around here are still using KA, so I don't worry about the laser alerts so much, but I leave them on just the same.

The K-band false alerts I get are almost always from the roadside "you're driving too fast" trailers that attempt to shame you by displaying your speed. I see each of these as a challenge to see how many digits the sign can display...

Ditto on my V1

I wonder if it's possible to reflash my Beltronics unit so it says "Old Fart!" instead of "K-Band."

I constantly get false laser alarm signals on both my Passport 8500 and my Passport SRX. On the SRX it will display the "LASER" alarm until I shut it off and then turn it back on.
