this might help http://www.electro-tech-online.com/g...unit-help.html but i just googled it i don't have any expereince. It seems you would have to pay the 25 but it looked like there was a way to short out the head unit

and if you do not feel like looking heres what the guy posted as the first soultion
"on the bottom of all eclipse units to my knowledge is two (2) solder
points that are visible through the chasis, if you take something like
a paper clip and open it up so you got a "V" shape, you can make
contact with these two terminals, and that should reset everything
back to factory specs, that is what eclipse does when you (as the
registered owner) send your unit in to them when it (the H/U) sceams
"call 800", or "help"... and this will save you a two to four week
wait, BUT YOU DIDN'T HEAR THIS FROM ME, I don't want someone at
Eclipse getting pissed at me because "I Let Out Their Secret"
I'm just don't feel it's fair to go so long W/O a toy. but now that I
let the cat out of the bag, i'm probally gonna be sorry because alot
of items will end up stolen now, and now their "ESN" means nothing, SO
FORGET YOU READ THIS AND SEND YOUR UNIT IN, YOU CANNOT FIX IT, YOU
NEVER READ THIS, I DO NOT EXIST, THIS THREAD NEVER EXISTED, IT IS ALL
FALSE, NEVER MIND, DO NOT READ THIS, just go about your marry little
way and pretend all this is a heap of Sh*t, and everything I spew out
of my mouth is false."
