Aftermarket Headunit, Radio Playing from Nav Speaker

[peanutmnm]

Hmm, looks like a bit more investigation is necessary then.

Had envisioned it being a big black box with Bose written on it. I'll have a dig around under the CD changer.

Think the HU might need to come out again as it's sounding a bit flat. Doesn't have that boomy sound the old one had. Will give me an excuse to see if I can identify which wire(s) feed the phone/satnav speaker.
