I know this has prob been covered before but i could not find any info. I have a 2004 tl non navi that I'm looking to upgrade with this unit. I was wondering if anyone with a 3rd gen has done it with this unit or another unit with the same features. It seems like it is a real pain to get installed. If anyone has pics of theres and any ideas for me I would greatly appreaciate it. I know your going to say why didn't i get it with nav but i bought used and could not find the one i wanted with nav, and i don't want a portiable unit. HELP
