    Thumbs down BMW cruise control is interfering with BEL STIR

    I have 2009 BMW E61 (535xiT)
    I finally found time over the weekend to install BEL STIR remote, drove the car with it and RD is going off constantly with K-band alert at around 24,229 to 24,247 Khz frequency.

    Couple of hours later after digging around my car I figured out that it is an Active Cruise Control (ACC) feature on my car that is broadcasting in above frequency range.

    I did test this RD before installation by placing it on the dashboard and driving around town for a couple of days - all worked well.

    My RD sensor was installed in the lower bumper grill, see the link below:
    2. Green spot - lower grill on driver side

    http://www.radardetector.net/forums/...w-e60-e61.html

    The three ACC sensors are located all around front bumper:
    two behind a bumper cover either side of license plate and 3rd, visible in the picture, is in lower grill on pass side.


    Looked at STIR manual - I can not segment K-band, only disable the entire band.
    Am I screwed?
    After spending $$$ on RD and 2 days installing it this RD is pretty much useless??

    Turning off ACC is not really an option since the car maybe spitting warnings all the time. Besides, I used it in heavy stop and go traffic and it really works great.

    Wouldn't it be great if RD manufacturers or dealers warn you before selling a product that doesn't work for your application?

    I did a lot of research before spending this much money on RD, including complaints about parking sensors interference (which I also have) from some cars, windshields etc.
    My car did not come up in any search...


    Any ideas?
    I do not see myself driving with RD on my windshield...
    Thanks

    I'm sorry vash68 but there isn't much that can be done other than mounting the radar receiver where it may not be able to pick up your ACC's radar. The STi-R is an extremely sensitive radar detector and your vehicle is emitting radar. When you try other mounting locations be sure to test drive in traffic as reflections from metallic objects (signs, vehicles, etc) may cause sporadic detections.

    If you had K band segmenting and disabled the effected segment then you might miss real alerts, not a very good solution IMO.

    1) try turning POP off and TSR on in case BMW is just pulsing.

    2) Kill it with Band Segmentation (be careful, dunno if the cops use K-band in that range in CO).

    3) Don't use the ACC, dunno if you can just do normal CC at X mph.

    Thanks for your suggestions guys

    1.@EscortRadar - are there remote RDs available with K-band segmentation?

    2. @verymanywelps - BET STIR to my knowledge can not segment K-band only turn entire band off and on.

    3. ran idea of disabling ACC by bmw dealer - they said it is not possible to disable it (even with reprogramming this car) - the car will be nagging with error codes.
    No option to use just CC part of it either.

    4. Will try turning POP off and TSR on, btw, what is TSR? Sorry, this RD is too new to me.

    Traffic Sensor Rejection. CA and some other states have these K-band drones that do quarter seconds pulses every few minutes.

    TSR just basically tells the detector to ignore any K-band under a half-second or so iirc. Dunno about spectrum.

    Yes, the International version of the STi-R Plus has K band segmenting but it is only 3 segments. That could certainly help you BUT you may miss police K band radar shots so I do not recommend it.

    If there was another capable version of a station wagon by Acura/Lexus/Infinity I'd jump on it, but there are none.

    4. Will try turning POP off and TSR on, btw, what is TSR? Sorry, this RD is too new to me.

    The car was in a shop for body kit painting, so finally got it today and I tried so far:

    1. TSR on, POP off, Autoscan mode - not helping.
    However, since I went this same route (to work and back) before with RD ON it must have marked my route using GPS software and now:

    1. While driving, the GPS blip on display is rotating constantly indicating that it is protecting me of an earlier marked location with false alert

    2. It only alerted twice in 20 min commute of K band threat from my ACC - so GPS must not have marked these 2 spots? or Automark mode de-marked those for some reason?

    3. It alerted me once of Ka band, but very weak - I did not see the source of it.

    So overall RD is still being pretty useless.
    BTW, it behaves the same with TSR on or off, apparently BMW ACC is not pulsing...


    1. Relocating RD sensor is a major pain - so will need a half a day over some weekend to do this - but if I have to move it inside a cabin then I will just sell it

    2. @EscortRadar - do you know which segments of K band can be disabled on Euro version of stir+? This may be my only way to go. I do not mind reducing some of K band sensitivity if that helps me run RD in only slightly castrated mode..

    3. I may have a shot at disabling ACC via BMW programming, researching this process currently, but every time I show up for service at a dealership, they will flush my programming to a new version and ACC will be back on.

    4. What about enclosing RD sensor into a metal box leaving only the forward view of the road open? Would that take car of it? except maybe for weak reflections from car in front of me?

    Thanks
