My poke radar wont work!

That's weird... It should let you use it. It probably is a glitch. Reset your DS and try again. If it still doesn't work, move to a new place and use it once more. If that still doesn't work, then your game is probably glitchy. If you used Action Replay on this game, there is yet another reason for failure.

Hmmm... Very, very strange. It most likely is a glitch, so try resetting your game, and trying it again. The pokeradar does not work in tall grass areas, it only works in the normal type grass, which is actually like weeds or something, but that is the only area that the Pokeradar works in. If you reset your game, tried again, and the Pokeradar still does not work, then I guess your game is just messed up, so see if you can swap it out with a friend or something.

Are you on your bike while in the grass?

Because I believe pokeradar does not work while you are on your bike..

If it is not that, it must be a random glitch.

Hope this helps,

No there is not to charge the pokeradar you need to walk a sertin amount of steps and in some areas you can't use it in.

It might be a glitch it might be the battery is screwed up

If you use it on your bike that is the poblem but otherwise itsa glitch and there is the possibilty that you can only use the pokerader in certain types of grass
Hope I helped
