DVD/Nav coming? Radio Update Available?

[UCF w00t]

I was poking around on TIS2WEB and found some interesting stuff I don't recall seeing before.

First, it looks like there's updates available for the head unit itself (in addition to the previously discussed PDIM updates).

20860506 0000FE51 New software for improved operation including fixes for "No Sound for Ignition Cycle" issues.
20862566 00006911 New software for improved operation including fixes for XM and PDIM issues.
20839881 0000EA1F New software for improved operation including fixes for XM and PDIM issues.
20825924 00004FEE Operating system

I'm curious what these XM and PDIM issues are. Do they fix the sound issue with XM? Does it remember the random setting for PDIM?

Next, after selecting the PDIM module, it gives options for "DVD Radio" and "Navigation Radio". Maybe they've been there before and I just ignored it but I don't recall seeing them before. Could this be an early entry for forthcoming parts? I know it's been mentioned that nav might come later (and denied, etc) but could this be a "leak"? Selecting it gives an error but it's interesting nonetheless... I wasn't able to find the RPO codes in the model guide. The equinox has them listed under both the PDIM and radio. PDIM gives the same error but the radio one actually works... same RPO codes listed. They also have the same RPO code for the CD/MP3 normal radio. They have the same updates listed for the PDIM when you select CD/MP3 under the PDIM module. Take this fwiw.

I sure hope so
