I have a 99'. This a direct fit - no splicing or anything, just slide your old one out and the new one in. And there is the GPS antenna. There was a wire to hook up to the speedo, but I never did it and it works fine w/o it. It is basically a Harmon Kardon Traffic Pro with slightly different labelling. As you can tell the screen is not huge, the audio is the primary way of telling you when to turn, etc.
It works good for what it is. It has the factory look. You have to input everything GPS with the knob on the right.
I'd recommend it if you can get it for $300 of less. It's an old system.
The newer Garmin Street Pilots and the TomToms and a few others out there are better - they have more features, but do not have the factory look - not sure how important that is to you.
HTH,
