I did buy the ebay "kit", but decided not to use it for several reasons. The main two reasons were:
1. The coloration of their fascia just does not match well enough to the volcano grey trim of the car. It is close, but not close enough. It's one of those things that would just bug me to no end.
2. The eBay kit does not center the HU vertically in the opening. Now, this may be nitpicking to some, but again, it is one of those things that would just bother me.
Frankly the eBay kit has great mounts that bolt onto the sides of the HU, but that's about it. The fascia (plate) piece is really, really flimsy. I mean to say, you could break it if you aren't careful. It is really thin. Also, it doesn't mount, in a way that makes it really secure.
So, they took it back as a return, which was cool. They have great customer service, and are really available to help the layman with the install. But, it just wasn't my cup of tea.
So, I ended up buying the unit from Nexxia in the UK, and getting it shipped in 2nd day air. The total, with shipping was around $80 or $90. I didn't really care about the plug adapter, as you only need to tap 2 of the wires, I just did that. I'm comfortable doing that sort of thing. It would make absolutely no difference if for some reason you wanted to disconnect and go back to original. I mean, just disconnect the taps, and your good to go. The EURO antenna adapter can be had on Crutchfield or eBay for between $10 and $20.
Now, I will say this, mounting the double-din bracket that comes with the Nexia kit is not for the faint hearted. There is NO easy way to mount it in the vehicle, and it will require a bit of work. My solution was fairly straightforward. I did the following:
1. I drilled and tapped a screw through the double-din cage and the plastic wall of the Porsche console. Then I put in a flat head, allen bolt into the cage. This was step one of initially holding it all in place.
2. I noticed that there was still a little bit of droop, with the unit mounted with the one-bolt method, so I ended up lining up the unit, and putting a super small amount of epoxy on the double-din lip on the left and right sides of the Nexia cage. Holding in place for about 4-5 minutes, and it was solid as a rock. If you want to remove it later, it should pop off with a heat-gun and a small amount of elbow grease...not that I plan to ever change it back.
Once the double-din cage is in place, and I put everything back together, the fit and finish is nothing short of perfect. It truly looks like a factory fit. The color is absolutely spot-on perfect. The vertical centering is perfect. The offset of the HU is perfect. There is no gap, or overhang with the face plate and the other volcano gray pieces.
So, it is quite a bit more work, but it is less money and, at least to me, a better overall fit and finish are possible with the extra time invested.
Basically, if you want the easy pre-fab no extra work method, go with the eBay kit. If you are a perfectionist and want the absolute best finish, with quite a bit of extra work, they go my route. It just depends on the level of involvement you are willing to invest in the project.
