Remote radar

I recently brought home an'87 911 that has a unique radar detector. I'm hoping that someone can help me identify the manufactured so that I can find out if it has ka and laser and if it can be upgraded. The sensor is located behind the rubber strip on the front of the bumper which has a series of lined openings in it. There is a small window display in the bottom of the tachometer. Mute, volumn and a city highway switch are mounted under the steering column.

It,s an invisable and really nice installation, but I'm not sure how reliable it will be.

I can't find any manufacturers ID anywhere...hope someone out there can help.

Thanks

It sounds like the K40. Check out the following site:
