Hello..

I bought a 94 Laguna last month, but it has no car radio in it. The battery is positive (+) grounded. Does this mean i have to buy a positive grounded radio or can i insert any radio? Or do i need a transformer or converter or something to stop the radio blowing up if i put a normal radio inside, because i have got a couple of radios but they all have a negative (-) sign next to the grounding on the information panel?

Any help much appreciated..

you should be able to get a polarity inverter to do what you want... i used a few back in the early eighties on postive ground buses..... another way would simply be to totally isolate the radio from the chassis, mount it in a wooden box or panel and do not hook up the antenna and it should work fine as well if you simply invert the power wiring....

...and I suppose that car drives on the left side of the road, too!

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

you could also isolate the radio from the chassis and connect it....but remember the ant will have to be a glass mt or it will back feed the positv into the radio ground.
