Since the upgrade from the Z110 I can no longer change the station presets, I'm stuck with the stations that were programmed prior to the upgrade. I also just installed XM and I can't change or program those presets. Anyone have solution for this?

Second issue, IPOD looks like it's playing but there's no audio. Suggestions?

Is anyone else having issues with the upgrade?

This is the first I've heard of the station preset problem... have you tried resetting your headunit? There might be some wonky settings left over that need to be cleared.

Also, I'm assuming your iPod was working on the unit when it had the Z110 software on it, correct? The reason I'm asking is that some people buy knockoff cables from eBay and then are annoyed when they don't work like the real thing.

Yea these are certainly strange issues. Certainly do a full reset of the unit.

Is there a special procedure for the full reset, or just a complete power disconnect?

Yeah, as far as the iPod goes, everything was working fine prior to the upgrade and the iPod works fine when not connected to the Z120.

Search "reset" in the PDF version of the owners manual.
