I'm about to fit a Nokia hands-free kit in my SE, which is straightforward done the bog-standard way. However, I would like to get the phone to play through the radio speakers. All the sources I've found say you need a very fancy (£40) lead that fits into the ISO connectors (which I haven't got). It's going to be a maze of bullet connections. I can see why a fancy lead would be required to have it playing through all the speakers at once. But could I do a simple job just using the front right hand speaker, by simply joining the speaker outputs from the Nokia kit to the front RH outputs from the radio? Or would the current from one damage the other? I'll be using the radio muting feature.
