<body class='hmmessage'><div dir='ltr'>A friend of mine tried to do exactly what you want with his TR3 Carl, and lost a GPS as a result of it. Just handling the GPS , and having the case briefly touch metal was enough to fry everything. For a car with touring needs and use of modern gadgets I'd suggest changing polarity for the trip - you can always change it back it if you want to show the car with positive ground.<br><br>Randy<br><br><div><hr id="stopSpelling"></div> </div></body>
