Found a photo on the Planet Subaru web site that shows the BLIS and cross-traffic detection units are mounted in the rear bumper. They are Continental units operating at 24.05 to 24.25 GHz according to the manufacturer's web site. As such, while the displays are in the rear-view mirrors, the sending units are at the far end of the car, facing backwards.

I also checked on police speed radars. These seem to run in three different frequency bands - X (10.525 GHz), K (24.125 to 24.150 GHz) and Ka (33.4 to 36 GHz). These are US police radar frequencies and which one is used varies with where you are. Note the only overlap in the K band. These frequencies are also used for other devices (like the automated doors in grocery stores, etc.) so false positives are often a fact-of-life for radar detection units.

However, in looking at the location of the Subaru's sensors and where your radar detector is located, I'd lay odds that you probably won't be the source of your own interference.

I've never been a radar detector user, but it would be interesting to hear if the above guess is accurate.

Thanks for digging up that information. Looks like a potential conflict on the K band but others have reported it doesn't seem to trigger false alarms.

The cross traffic radar doesn't need to be on unless your in reverse, so hopefully it's off in normal driving. The blind spot detectors are probably the same type of radar?? and more likely to cause interference.

I borrowed the photos from Planet Subaru and have attached. The module is a Continental SRR2-A and you can check the specs for it at the manufacturer's web site at www.conti-online.com. It looks like the BLIS system and cross-traffic use the same modules.

Just a note: p. 9 of the 2015 EyeSight Owner's Manual directs the owner not to install any accessories in the 'prohibited area' which is the middle 50% of the dash. It goes on to direct the user not to place any object on top of the instrument panel or the EyeSight system may not function properly. Has anyone suspended a radar detector in some manner from the overhead console? Seems like it would be relatively easy to find a 12v line inside the console to power a radar detector.

I use Waze, especially on road trips. Have found it to be very reliable.

I have a different twist on the tread. I want to install a rubber block on the bumper sides and do not want to block the bsd or side traffic radar.
The picture indicates it is on the back of the bumper. I thought it was on the the side at the rear of the bumper. I'll need to experiment with some tape before a permanent install.
Parking on the streets of SF is reason for the rubber blocks. Some people use the braille plunk-to-stop method while parking here.

I've had an Escort mounted below my rear view mirror (using a blend mount) since I got my '13 OB with ES and have had no problems with either.

Ahhh... I was on another thread talking about the same thing...

I have a 2018 Outback Touring and just purchased an Escort Max 360c. I couldnít wait for my mirror mount to show up to try it so I installed it really low, almost on top of dash, center of windshield using the suction cup mount to try it.

Right away it started reporting active Ka Radar behind the car! My whole drive home it would go off reporting Ka behind the car. I thought maybe it was picking up other cars sensors so I turned off to a road where I was the only one around. It continued to go off at almost regular intervals.

I finally removed it from windshield and placed it on passenger seat. It stopped going off. I then help it up near my right ear, center of car, and it seemed to quite down. Iím going to try it again today.

I am thinking the Escort Max ď360cĒ is very sensitive and itís rear detector, when down low on windshield (basically on dash) is picking up the Blind Spot Radar???
