supna Posted June 18, 2003 Share Posted June 18, 2003 The band expander is only for the Jap headunit. If you are getting a new H/U then you don't need the expander. Link to comment Share on other sites More sharing options...
Digsy Posted June 18, 2003 Share Posted June 18, 2003 It needs a power supply so I reckon it should go to +12V. I believe they earth through the aerial lead. Some of them also have an on/off switch too. Link to comment Share on other sites More sharing options...

Simon Posted June 18, 2003 Share Posted June 18, 2003 Keron, no you don't as long as the new unit is a UK unit. The expander is to allow japanese imported radios to receive UK frequencies, there's a difference of about 16Khz. Link to comment Share on other sites More sharing options...
