The Becker Mexico is about the only retro style headunit around at the moment the cheapest ive seen it is from DNA car audio for £899 but it is fully loaded with loads of technology and sat nav.the Panasonic CQ-TX5500D was out in 2002 that was an expensive bit of kit when it came out ,it can still be bought new in the US for $900 !!!! but it does look a bit Dr who OTT !. Vintage wireless,Manchester can convert your old units to FM for around £100 then you would be able to use something like a Griffin i trip to pipe your ipod tracks trough an fm frequency and listen to them on your old skool unit
