I purchased an antenna from crutchfield to do my dd install it was a male female and two prongs sticking out. i took out my broken bose hu from my 05 g35x and it only has the two prongs. im trying to install a dnx 8120. but now i have no antenna. the one from crutchfield doesnt matchup. what is the proper antenna for my car? and where is the best place to ground the wiring harness ground? ive been searching threads to no avail

 

I got the Bestkit BAA9 antenna adapter. For the ground, there is a screw right under the seat warmer buttons, behind the shifter. Seems to work.

 

ok. so you had to extend the ground wires? thats exactly what i need thank you
