Sorry to tell you but there is no such thing as a radar jammer. Besides if you are reading them with a detecter don't you think with the type of system they have they already got you? I know some one that will give you a whole bunch of money if there is a Radar jammer that actually works... Laser jammers are a whole different thing. I can tell you from experience that they work!!! Tested and proven countless times by friend cops and by ones that did not know. Check out the web site..

Here is a pic. Look at the upper grill on the outer sides and you will see them. Best money I spent even though I don't speed on purpose. Radar detecters in my state are illegal but a Laser jammer is not because it is regulated by the FDA. Kind of funny but works for me...
