Swap out N1 for N2 Will it plug and play?

Hey there pros got a little speedbump here im trying to cross. Got my Pioneer N1 in my 99 Lexus GS and Pioneer N2 in my 02 Toyota Tundra. I want to swap out the units. Meaning I want to use my N2 in the lexus instead and use the N1 in the Tundra. I use more of the navigation in the lexus on a daily basis and the N2 has the updated software which has more newer locations whereas the N1 doesnt. I already tried updating the N1 with new software but that was a disaster because it wouldnt let me watch DVD's or program while driving. Well to make it short i had to reprogram the N1 back to factory. So if i was to swap out the brain and head units with each other are the wiring setup or installation the same? Will it just plug and play?  I would hate to take it to a shop and spend money just to have them swap out the units if i can do so myself. Help me out. Please email me at vuster2120@yahoo.com thanks.
