2002 Is300 Audio

[Rory]

Hi guys, hope all is well, it's been a while since I was last here, haven't been on the car scene for a few years now

Just one question, which kit do I need to put aux in onto the original head unit as my cd changer does still work so no point changing the unit, just want to add USB and 3.5mm aux in

I've seen 2 kits on eBay but one says 2004 onwards, the other says pre 2004 but not compatible with 6 disc units?

Plug and play preferred cos I don't do snipping wires

Car is non nav, 13906 unit (I think)

Thanks in advance
