The radio band frequencies used in Japan are different than those in North America; there is some overlap, but most people end up replacing their JDM units. It was fun listening to American pop in Japanese on the mini disk that came with the unit for a while, but I've had enough of it now.
The questions:
- Which years of US market 80 Series stock radios will plug in to a 1990 JDM HDJ81?
- When did the US market 80 Series stock radios start coming with CD players?
Thanks, -Steve
