i have done a heap of research on these exact models as it was exactly what i was looking to do to my lib...
the pioneer was recommended above all as the top model...the eclipse was best bang for buck...double din facia phat is your man.
have you considered buying a top spec dvd / double din head unit (about $750 for the P1450) and then installing or using a top spec'd nav sytem...will cost you much less to buy separately then as a joint purchase....and how many times do you actually use a nav system?
yes you will have it running all the time but how any times will you actually need to use it to justify the $1k price difference
