The Microtune AM/FM/RDS module is the SAME module that is used in the HQCT radio. That's what I'm looking to use. Datalex is not willing to sell the parts to their design (programmed chips etc), so it's either buy from them (expensive), or integrate the Microtune module ourselves. I'm going to attempt #2 and see how far it goes.
The GPS will be a module that is cheaper than the U-Blox stuff. I haven't picked one yet. I will design our board to interface with these directly. Since they all have a carrier board (and are not just IC's), they will not even be a physical part of our design, meaning that it's easy for someone to say YES i need one or NO i don't. Saves them money. Not everyone needs or wants GPS, and it's easy enough to make an option.
