replacing the dead Eurovox AM/FM/CD stereo with a modern FM/Bluetooth/MP3 stereo unit, desoldered the multi-pin connector
from rear of the Eurovox to make up a new interface harness between the Eurovox stype connector attached to the internal harness
and interface it to the new JSD-520 stereo, which has the ISO connector.

Addendum: 
the FM/MP3/Bluetooth stereo had some intermittent issue, so replaced it with a Nakamichi AM/FM/MP3/BT stereo. 
Much better sound and it has AM reception which is very useful when driving out in the country.
