Head unit radio reception (Phase 3)

[Eeyore]

Is this the same on phase 1s? It could be the reason my radio has crappy reception unless the I hold the plug right in.

if you have to hold it right in them that sounds more like a connection problem! This is an amplifier problem so the fact yours works fine when its held in suggests it works fine when there is a good connection as opposed to the problem these guys are having when the connection is good but the reception is poor!
