Where can i find a replacement screen for a cobra 5550 trucker gps

SOURCE: Roadmate 2000 power supply over-voltage

The roadmate operates on five volts dc. Look at the back of the unit and it says so there. Inside the cig lighter plug that comes with the roadmate 2000 is a transformer that converts 12 v dc to five v dc. You used the wrong charger and put twelve volts across a unit that only handles and requires five volts.
Check to be sure that you used the correct charger. it sounds like you did not. It may be possible that the charger was still wet or was damaged when wet and that it shorted out.
Radio shack sells a charger for the car that is made for magellin roadmate 2ooo. It includes several different tips including the one that fits this gps unit and the output is five v dc. It is possible that what you smelled was the charger cord and not the gps unit itself.
I used the wrong charger on mine and had a similar problem. I bought this charger and all is well. radio shack cat no is 20-151. Get it soon because it is on sale for about thirteen dollars and is discontinued. As of today, sat jan 12, 2008 they still have them in stock at most stores. You can call ahead or look online and it will even tell you which stores have them, or you can order online as well.
No, if it is the gps unit titself, do not try to mess w the circuit board. Its cheaper to buy a new one. good luck to all w similar problems and ALLWAYS check to see that voltage and ac or dc symbols, as well as polarity, match up. If not bring your electronics to radio shack Before powering up and they can check all of this ffor free if you are unsure.
