Antenna Adaptor for 2002 Volkswagen Jetta

Written By Marc M, Manchester, NH on Wednesday, January 22, 2014
Crutchfield Customer Review (What's this?)
 
For the life of me, I couldn't get the antenna adaptor to stay secure to the antenna lead. They went together, but there was nothing to really secure the two parts. I ended up wire-tying the antenna lead to the plastic flange on the adaptor in order to secure them - hopefully it stays put!
Pros:
Works when I finally got it attached
Cons:
Wouldn't secure to antenna lead

Simply and trivially does its essential job

Written By bobatious, near Seattle, WA on Wednesday, January 15, 2014
Crutchfield Customer Review (What's this?)
 
Once wired correctly, this adapts and amplifies the 50 ohm connection to the car's antenna with proprietary connector, to the 75 ohm connection with usual motorola-style car jack in the aftermarket head unit. It works well and the resulting reception is at least as good as with the factory (VW Monsoon) radio, which did this internally.
Pros:
Simple, works well.
Cons:
None - does require power connection to do its (amplification) job

I'm not a mechanic, but I wanted to install my stereo myself. I'd never done anything like that before. This adaptor didn't come with any instructions, and while it didn't end up being hard to figure out, I would've appreciated some direction. Besides that, everything sounds great and comes in perfectly.

Used this in my VW Eos. Thing is, my factory had *two* antenna leads. This is only a single one. I've seen a double-adapter but couldn't find one in the US. This seems to work okay, but I can't help but think my reception is suffering a little. I don't listen to radio much beyond NPR these days anyway.

This antenna worked perfectly for my 2007 VW Passat. The only reason I am
knocking off a star is due to its design (& no fault of Crutchfield). Attaching it is
simple as pie, but I found if you need to disconnect it for some reason, it was a
REAL challenge & a bear to do so. You also have to be very careful not to strip it
when trying to disconnect it. Other than this, it works great and radio reception was
good.

I used this for my 2006 Jetta. It installed pretty easily except that the connection part to the factory antenna didn't quite fit. The small tabs on the black piece weren't quite the right size. I did make sure that I got the right connection because I have satellite antenna as well.

After connecting the blue wire to the antenna power source off the radio wiring harness I got a crystal clear signal and everything worked great.

Antenna works fine

Written By Artfield, Rochester, NY on Monday, August 24, 2009
Crutchfield Customer Review (What's this?)
 
VW roof antennas cannot stand up to carwashes - I've had 4 so far. When that happens I lose my NPR (AM), so I was careful to maintain the signal.

I noticed a 'flea clip' on the end of the antenna lead, so I wired the blue wire from the radio to the adapter, snapped the clip into the empty corresponding space in the adapter and the antenna works fine.

I'm certain that the signal is stronger than with the o.e.m. setup. Unfortunately its increased sensitivity picks up some alternator rf on AM. Mu metal, anyone?

This device works well.

Works, as long as you know where to hook up blue wire.

Written By Ritchm, Portland, OR on Monday, February 16, 2009
Crutchfield Customer Review (What's this?)
 
Car-2003 VW GTI I got this as part of an installation kit for a new stereo. First off, there were no specific directions on where to hook up the blue wire. In my case, the harness adapter Crutchfield provided had a blue wire that was labeled antenna and the stereo also had a blue wire for a power antenna. I made the mistake of hooking it up to the harness first. This gave me FM reception, but no AM. I managed to get a volt meter on the wire while the stereo was on and it didn't have any voltage. I also checked the blue wire from the stereo at this time, and it had 12v on it. I had to pull everything back out so that I could solder it to the blue wire from the stereo, then I got both AM and FM reception after that.

One thing that worked fine for me is this antenna. I didn't experience the things that other reviewers had (phew!). I have a 03 Jetta with Pioneer DEH-P3000IB from Crutchfield - the tech support guy actually told me to hook the blue wire to the mystery wire on the harness. (note: there are ground, power, and speakers - those are self explanatory. There's a suspicious one that I haven't the slightest idea what it's talking about -- but Crutchfield said to hook that to the blue wire from antenna.) I was able to get AM and FM just fine... maybe it's picky about the radio or model year that goes with it?

It works very well. I followed one of the reviews and did not hook up the blue wire when I installed the radio on Thursday night. I had no AM radio reception. This morning I pulled the radio out , removed the blue wire mounting clip, and tied it into the factory and Crutchfield supplied harness antenna power wire (blue w/white stripe). I now receive the AM signal better than I did with the factory radio.
