I have a 98 S70 with the SC 816 HU. Am I wrong to think that I could splice the factory CD changer cable, find the Left and Right audio input and solder a AUX cable that could connect directly to my iphone? I have been looking at all these Blitzsafe wiring units http://blitzsafe.com/catalog/volvo/vol-/-aux-dmx-v-1/prod_241.html They seem WAY overpriced. Is there any reason this wont work?
Thanks!
