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
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...
I do not see myself driving with RD on my windshield...
