how to change antenna on 09 JSW
This is a how to on the antenna on an 09 JSW. the AM antenna on later cars is in one of the rear side windows, as the FM antenna is on this model.
a few years ago, my AM radio quit, and lately the Sirius XM has been increasingly flaky. last fall, the whip had deteriorated so bad it was held on by the plastic, and was whacking the car. not a pretty sound to hear driving down the road.
this photo is the after shot. (it was a frosty drive to work)
I ordered this new base and antenna from www.vwpartscenter.net I ended up calling (August 2014 edit: recently the vwpartcenter web site indicates they do not take orders over the phone. you could message them or e-mail a request for current pricing and part numbers) , but you could order online or stop by your local dealer. this is a little pricy, even with the partscenter mark down. it was just under $180 for the antenna base, whip, and an adapter needed because they updated the connector. (vwpartscenter will take a VW dealer only dieselgate loyalty card for payment)
5N0 035 501 seems to be the part number for the updated base.
You also will probably need the whip antenna, you can get an original, or find one a little shorter if you like that look. (AM will work best with the longer antenna)
the adapter is shown here: http://www.ecstuning.com/ES12175/
part number is 6Q0-035-575-K google will find you one.
more about that later.
I was a little hesitant to pull the trim apart, but then thought, heck this car is six years old, what is the worst that can happen?
so open the hatch and get to work.
the trim at the rear of the headliner has to come off. just one part. I used a plastic scraper from harbor freight. lift the gasket and pretty easy to pull down the edge of the trim.
now the trick is to pry down to make room to get your fingers (or a large screwdriver or similar) and pry or pull down.
the trim just pulls straight down. you probably could pry with a screwdriver, or trim tool, but these clips just pull off. it was harder than I thought it would be, but seems pretty sturdy. again, it wants to come straight down, and not to any angle.
with the trim pulled off, now on to the rear of the headliner.
pretty easy to pulldown the rear of the headliner far enough to access the bottom of the antenna base. in this photo you can see the antenna leads, connectors, and the clip that holds the coax wires to the metal roof.
A better view. you can see the plastic adapter on the clip, and the nut that holds on the antenna. takes a 22mm wrench. I used a box end. only have to use the wrench a couple flats, then comes off with your fingers.
the plastic adapters have a little release to press (I used the edge of my thumbnail) but I did not get a clear photo of the release.
This is the bottom of the old antenna. you can see the square shoulder on the top of the threaded part that holds the antenna on the roof. The hole in the sheet metal fits this square shoulder. If you did not care about the satellite radio, but wanted only the am radio, you could order just the am part of the base. which is quite a bit less expensive.
You can see the notch on the white plastic connector which keeps it mated to the vehicle half. They are color coded and keyed differently on the outside of the round end of the connector The replacement parts for this model need to have this plastic part replaced on one of the cables.
I did not document which one, but it is the one that does not match the ones still in the car. I think the white one was fine, but you better double check.
One of these has to come off the new base. Once you figure out which one has to be changed, pry out the little purple plastic part. it will try to head for the hills, so keep an eye on it if you want to ever see it again.
I used this screwdriver to pry off the purple plastic retainer, and then used it to pry the part that looks like a triangle on the green plastic connector adapter.
With that part bent up, the plastic adapter comes right off the actual connector.
The 6Q0-035-575-K adapter slips right on the end of the cable, and the red plastic part shown above clips into place.
The cables slip in the hole from the top of the roof, and go together easily.
With the antenna just slipped in, go make sure the radio works.
Happy day! All bands back in business.
You will want to stow the wires back where they came from, and replace the nut to hold the base back in place. I had a friend hold the antenna in place to make it easier to install the nut. Pay close attention to the aluminum adapter/washer, and make sure the leads coming in the car are in the apropriate place, and that the key in the nut adapter is aligned with the slot in the antenna base.
Finger tight, and then a couple flats, not sure of any torque spec, but you don't want to go mad and crush the wires or the adapter/washer.
If you got ambitious pulling the trim off you may have to put one or more of the clips where they want to be on the trim before putting it back. If they are stuck in the metal you can pull them out with a pair of needlenose pliers without much trouble.
Carefully align the trim to the holes where it came from and press back into place.
