I think it's asinine that it doesn't include RDS, especially the Z1, and all Pioneer Navigation units. I wonder if there's a code...
Look at this Kenwood unit for $1000. No navigation, yet...
1. RDS capable
2. DVD capable
3. HD Radio Ready
4. Security Code
5. Dual Zone for Front and Rear
6. Advanced Crossover (remember SFEQ - Sound Focus Equalizer?)
7. Navigation Input (so it's Navigation Ready)
8. JPG/MPEG playback
9. Included Remote
The Navigation function is another $800,

It's NavTraffic capable, though...
There's also the MusicKeg Hard Disk add-on for it, which WILL INTERFACE WITH THE PC!!!
Pioneer's navigation systems are very good, but lacking in the little grab-me features. RDS is just one of them. It doesn't cost much to add it -- many tuners have the demultiplexing scheme built in.
RDS is a 57kHz signal on the FM carrier signal (the signal that you tune in to, like 99.9 or 103.5) with digital information that gets decoded. Chips to decode it cost pennies literally -- then its all controller-based from there.
