hey guys just bought the add on navi for my kenwood ddx 6019..install looks easy enough so im gonna attempt this my self..where did you guys mount the navi box and antenna? any suggestions/comments will be greatly appreciated...thanks

 

i put the unit under the dash (theres a clip on panel down there) and ran the antennae wire up to teh passenger side dash (lower corner of windshield). works great there.

 

you can also put it in the glove box.
But in the radio housing there is tons of room. I had my XM,Ipod controler and Nav all in there plus radio.
