Hi,
Maybe a silly question, but has anyone ever considered or attempted to connect a pc/phone/mp3player with an analog audio output directly to the cars speakers, without runnning it through the hu? There would have to be a switch somewhere on the dashboard to switch between hu input and 'custom aux' input. The only drawback is that the display and steering wheel controls are useless (but the display is useless anyway if you use soft- or hardware emulation on the CD-changer port).
It seems to me that this is a cheap solution for ppl that have a Tunerlist on a post-2000 renault model who want an AUX connection (like myself

)
Any thoughts on this?
