Best NAV/Ipod/Bluetooth Upgrade for 04 w/JBL?

[SoCo Toyo]

Just now buying my first 4runner. Coming out of a more than loaded 07 Tundra Limited. Getting into an 2004 4runner Sport with the JBL sound system. Would like to have some of the features of my Limited back. What is the best replacement head unit for my JBL that would give me NAV, Ipod and Bluetooth (and ideally another input for satellite radio). Have the left steering wheel controls for the JBL but if its easy would like to add the right side blue tooth buttons as well. Want my backup camera back if possible. DVD would be a bonus but not necessary. Read through some of the posts but figured if someone with my situation could hit me back so I can skip the trial and error portion of this process it would be appreciated.
