I did a hot wire job from the battery to my gps acc. plug-in and now when I plug in the gps, the screen goes haywire. I can take the same gps and put it back into my truck and it works fine. Any suggestions?

Did you cut a cigarette lighter plug off the the wire to connect the wire to the battery? If so, that plug has a 5V regulator in it. The GPS is getting 12V instead of 5V.

If that isn't the problem, check that the polarity is correct.

Thanks. I'll get the polarity checked and see if that's it

OK, Appperantly I am getting 12 v to the plug ins instead of 5v. I think I need to find where that extra wire by the radiator is that everyone talks about and wire into that

That's still 12V. You need the cigarette light plug with the 5V regulator or another 12V-5V converter.

Ok. Well, I had it wired this way for 2 years and it worked. I guess I got lucky. I think I will have to wait at this point until I get home and double check. I didn't cut the plugs off so if there is a online 5 v converter, i will make sure these are still ok. Thanks for all the help, let you know tomorrow if I have sucess!
