There should not be any need for the player software to be modified at all, save perhaps in the case of the weatherband receiver. The PIC in the tuner unit has a standard protocol which the player uses to tune it, receive rds data, and so on, so as long as this protocol is adhered to the system works as is.

Anyway, from what I gather sans datasheet, the replacement tuners from microtune have virtually identical interfaces to the original one. It's all set up by I2C in the tuner module, and Hugo is more than capable of making any minor mods needed.

He does, after all, have a bit of experience in these matters.

As far as weatherband goes, I still need to look into this.
