Difference btwn M20-X and M40-X?

[smokedhen]

Does the M40-X just comes with two extra plug ins for the rear?

If you order the M-20 you get to transmitters. If you order the M-40 you get 4 transmitters. You can place 2 up front or 2 in the rear. If you have a large vehicle and want the best covearge you can mount all 4 in the front. Make sure you mount them according to the manual.

I was wondering the same thing. Can you add to an M20 and make the M30 or M40? Does the M20 control in the car have extra inputs?

[outrun]

The M-20 does come with 2 extra inputs if you wish to upgrade to an M-30 or M-40. There really is not an M-30, unless you just bought one transmitter from someone.

Thanks for the info. I was really impressed with the difference that the transponder over the plate made in your M30 tests.

[outrun]

Yeah the m-30 does great but you have to find someone that has an extra head. Also the reason I have it placed there is because as the officer is aiming at the plate as I get closer his beam gets narrower so as long as there is a transponder right on top of it, it will continue to jam.

Can three be put in the front, and one in the back?

Can three be put in the front, and one in the back?

yeah but that one on the back will hardly offer any protection their so it's better off on the front

The only jammer that I have heards of jamming the back is stealthjamals zr3 from 0-400 feet.

I would have to say any other jammer, unless you are willing to spend huge bucks, you are toast from the back
