Thanks for the info. I haven't been able to find that forum post you mentioned, but I did find some posts that indicate the GEX-P920XM supports multiline display. Though, that seems to depend on your HU too.
I found a thread on Crutchfield's forum where a guy found that if you plug that to a DEH-P5900IB, the second line can only display channel name - but if you connect it to a DEH-P4900IB and toggle the two-line display to be the two lines you want, then move it back to a DEH-P5900IB without disconnecting the power, you'll be able to see the two lines you chose - until the next time you have to disconnect the battery, after which the stupid P5900 will go back to having the second line locked to channel name.
Stupid Pioneer.
I just checked the owner's manual for the P99RS. Oddly, for Sirius it tells you each item you can set the display line to show using the D/Scrl button, but for XM it just says "Press D/Scrl to switch the XM display" with no details given about what your choices are.
I also saw that it tells you how to use Instant Replay for Sirius, but no mention of it for XM.
