I have a 2004 es330 with no nav and I want to install a Denso E7006 navi off a toyota, will this fit perfectly? Is it plug and play? Do I have to buy connectors and a gps antenna?

 

yes it will fit but i recommend getting the lexus es330 unit. the lexus unit has a special amp that mates with it for voice nav. the voice nav in e7006 unit mates with a 10 channel jbl amp with voice nav in the amp and doesnt work well in a lexus.

you can add a 6 disc external changer in the console . the 4 disc changer in the e7006 is the usual fujitsu changer like the is300 and 98 to 2000 lxs470. fujitsu doesnt know how to make multidisc changers very well. yes the nav unit is made by denso but not the 4 disc changer part. so its best to go with the es330 unit with 1 disc player made by fujitsu . the dont break as often as the 4 disc fujitsu in the e series denso units. . the 6 disc console changer is made by pioneer and lasts many years of carefree playing.
also the 1 disc lexus unit takes multiple peripherals daisy chain style to the cd changer port whearas the multidisc changer doesnt since it already has a multidisc 4 . they stopped the cd changer port on e7006 from functioning as well as the lexus 1 disc unit cd changer port.
i have done many installs of both types and never get complaints about the lexus es330 nav. i quit retrofiting the e7006 as it is very quirky. i get them back to work on with 3 and 4 things not working correctly. like the map wont eject. the changers broken. the screen motor doesnt work. also the connctor for rear view camera and the bluetooth all were put on the same connctor which is hard to even buy from toyota. the es330 lexus unit has a seperate 6 pin camera port and 8 pin mic port.
