Hey all.. First post so go easy! (And apologies if this has been asked before.) I'm about to purchase a 2010/2011 KX-S AWD for the family, and I'm wondering if anyone here has replaced the CD with a GPS/DVD unit. Like the Polaris, Alpine, Pioneer, etc.. units. If so is there anything I should look out for, or any units that are better than the rest? I want USB, iPod, Bluetooth, Sat/Nav and so on.. Cheers and thanks Trav.
