This Has Probably Been Asked Already But If I Have All The Components For Navigation What Do I Have To Do To Add It. Is There A Lot Of Wiring If So Where Can I Find The Diagrams. Is It True That U Need A New Back Windshield W/a Antenna In It For Navi. I Have A 99 Tl W/out Navi I Am Looking To Add It.
Any Help Would Be Appreciated Thanks

 

I know for a fact that the Radio antenna is printed on the back windshield. But I'm not yet sure where the Navi antenna is. However, the front windshield also has a printed wire in the top-center, right next to the rear view mirror. My current guess is that, that could be the antenna for the navi. But its only a guess. And if thats the case you wont have to replace the rear windshield, but might have to replace the front windshield.

Then again, if you could get the antenna seperately (If its possible), you could just stick it on the windshield or try some other contraption instead of buying a new one.

 

i always thought the black dots were just to shield from the sun? i think there's a different "design" in the back for the antenna
