I'm about to purchase XM and am considering whether not I should get the direct input into the Navigation system or just use the FM Modulation. Is the sound really a lot better with the Nav input? I've heard FM is pretty good.

The problem is that you won't know until you do it. The direct connect (Blitzsafe) is very good and is worth the extra money IMO. Just go for the best while they have the dash opened up and you won't be sorry.
