sound inside my dash. But the thought of giving me $2k G4 a whack did make me laugh. I'm sure it wouldn't hurt it, but can't help here. Sorry.
On a side note, within 30 minutes of opening my G4 package I was already installing mine and I haven't had any hardware related problem (the AM issue is apparently a SD update, should be fixed or I'll just go back to the last patch). Hope you two get it all figured out.
