how do I reset "service now" sfter an oil change?

After about 3 months of inactivity, i tried to start car it didn't respond. Had it towed to the Dealer for service. Dealer said that the battery that I had purchased from them last year couldn't be recharged. This didn't sound logical. Needless to say i purchased a new battery from them and they did'nt prorate the value for a possible discount. Is this true that a recommended battery cannot be recharged?

I just purchased a GTS 4 with PCM- Nav, disc changer and iPod interface.  I've connected 2 different iPods to the interface and neither seem to recharge directly from the PCM iPod interface i.e. I need to remove the iPod from the car and recharge it in home.  Is the PCM iPod interface designed to support recharging and if so is there some trick to making this work??  Your inputs are apreciated!
