SatNav and police radar detector combined

Ok, so I was driving down to the kingdom of Graz today and was very grateful for the warnings given to me by my SatNav of fixed speed radar sites to try and help me fight off the advances of the Austrian treasury.

Shame, thought I, that I don't have a radar detector to help me avoid the buggers sat by the side of the road pointing hair dryer type devices at me.

Anyway, what I was wondering is, does a device exist that combines the two?

I haven't seen one but I would bet that it would be a surefire winner and fly off the shelves of Saturn, Media Markt et al.

Updated, most of the text was missing from original post.

I think they do exist, and even detect radar, lasers, and whatever else the buggers use, but the devices are now illegal to use. You can own them, you just can't use them! In fact I think in DE the law even restricts what your sat nav is allowed to do to warn you of approaching fixed cameras. Of course it knows your speed, and knows the location of fixed cameras, and generally they know the speed limit in any area, but they're not allowed to produce any sort of warning that you're breaking the law.

Radar detectors are illegal in Germany (see § 23 1b StVO).

I have not heard of or seen a combo Satnav/radar detector. TomToms come close as they have the automatic update feature
which can update the maps speedtraps and cameras placement info based on actual semi real time user inputs.

My Tom Tom not only gives an audible warning when I'm approaching a speed camera, it also flashes red on the speed reading when I'm exceeding the posted speed limit.

Likewise in Austria Allers but in Germany it just turns red, unless I havent been past any speed traps in the Fatherland.

You can make it sound any warning noise of your choise. You just have to configure it to sound the alert when you are with-in
100m of the POI. Then when you get near the POI it will sound and flash.

I did only mean fixed ones, like in the overhead gantries, it flashes a speed limit sign and gives a loud warning. You have to tell it to do this in the set up menu though. Obviously it doesn't detect the sneaky mobile ones.

Hmmm, mine does exactly that in Austria, need to find a known speed trap in Germany to test it or need to look at my setup per country perhaps?

But that's not the same as what the OP was talking about, ie. devices that can detect the laser/radar beams on the portable devices and produce enough of a warning so you can slow down. These detecting devices are illegal.

I realise that, I was replying to your statement that "they're not allowed to produce any sort of warning that you're breaking the law." which mine does by flashing red when I exceed the posted speed limit.

The legal status is weird in a way. Surely it is better if somebody detects a speed trap and actually slows down, rather than carry on speeding but getting a ticket from the plod?

It certainly is, but that's the plod. I was pretty sure that it is illegal for these devices to warn you of approaching speed cameras, but maybe that's just BS and it's really only the speed camera detection things.

The warning comes very short time before the device & it warns even if the device is for the traffic in the opposite direction only. The solution is of course not to speed...

The programmed speed limits are not always correct...
