1. The cloth seats seem a bit stiff. Do they soften up over time? It's a Jeep, everything is stiff.
2. Is the seven Infinity speaker system worth the extra money for the upgrade over the standard six speakers? (I suspect it may be when the top is down, but could use your help on that). 7th speaker is a subwoofer. So if you want more bass response in your music then Yes.
3. How good is the Garmin Nav system like that comes in the Media Center 430N package? I've got NAV's in my Acura and Suburban, and they both suck. They don't find any business I type in. Won't want to spend the money on the NAV in the JKU unless it is better than my portable Garmin (even then, might not do it). There are better after market options for less money.
