I cannot comment on the Power Antenna install. I have not looked in the fender where the front antenna is installed. When you get the unit, trial fit the product first. If it does not fit, email us and we'll credit you on the antenna.
The CD changer combo you purchased is correct. It is the smallest changer we sell. It also has 2 RCA inputs (stereo) on the converter itself. On our converter will be a small wire, when grounded, it will switch the factory radio from the cd changer audio to the RCA inputs of the converter (you can feed your in car video sound or MP3, or whatever on these RCA inputs).
To install the changer. Remove the trim bezel around your radio. It snaps out. (carefully do this). There will be four 8mm screws holding the radio in place. Remove these screws.
On the back of the radio will be a blue molex cd changer plug opening. (or black)
This is a picture off a CIVIC, but the port size and shape will be the same (see arrow)
Plug in our converter, plug in changer cable to converter, run down GLOVE compartment side, run down door sill, mount changer under seat, plug in changer. Turn on car. You are done.
Good luck.
