S3mad_dude - I've just checked and my car has a CD changer in the boot! Yes, I know. In my defence, I bought my car 4 years ago, drove it 80 miles, blew the engine, put a new engine in, blew that within 3 miles, and after that it's been in storage until a lot of work to restore it to road-readiness these past couple of months.
And darkfibre, I see what you mean - these iPod / MP3 connection things are about 40-50 quid on eBay. Only problem then is you choose that over your CDs (or switching the plugs regularly...).
Although, you might have a point there. Might be time to dig out the late-90's tape packs!
Cheers fellas,
Greg
