I have been using Pioneer decks for nearly 10 years and they have all been single line displays when it comes to XM. I have used the older XM direct units: XMDPIO100 and the gex-p910xm and something else that I can't recall.
I wonder if the p920xm will give you a two line display, but I doubt it. (if anyone would chime in).
Now, I could be wrong, but I doubt the P99 will do 2lines for XM
For the RW/FF feature, that comes with the new tuners that are out now, the SXV100/SXV200 and from what I read online last week, your HU has to have the "SiriusXM" logo on it to be compatible. Also, from reading, if you HU has the "SAT ready" logo, it will not work.
Hope this helps a lil, even though I didn't answer for question directly. I wish there was more support or more talk out in the forums of what actually works, line display details, compatibility, etc.
