My apologies in advance for asking what must be an oft-repeated question. Having left my audio system untouched since I bought my S3 new in 2000, I thought it was about time that I upgraded the standard (pre-wired) 6 CD changer so I can play them new-fangled MP3 thingies with the standard Concert head unit. I've had a look at the Phatbox, but I can't justify the cost. Not being an expert in these things, I would welcome any advice on the kit I need. I've had a look at the Sony CDX-T70MX (which seems to fit the bill) and wondered whether anyone out there has any experience of this? Or perhaps there's something better (and cheaper)? I'm all ears! Thanks in anticipation. G.
