Hi Everyone,

I have a slight problem that I'm hoping you can help me with. After doing research on the forum about the necessary parts to buy before installing my aftermarket stereo, I'm kind of stuck.

I have an '05 Roadster WITH navigation, and I've already pulled the stock radio/navi unit out and tried to install a Sony CDX-GT57UP head unit. Per the forum, it looks like most purchased the Scosche VWA3B antenna adapter, so I did as well.

However, it doesn't fit! It plugs into the Sony head unit just fine, but the other end isn't compatible with the factory antenna connector.

I'm not sure why this adapter has worked for others and not for me....maybe the navigation has something to do with it? Also, I have a convertible, so I have an antenna in the rear (not sure where the antenna is on the coupe's). Maybe this has to do with why the adapter doesn't fit? (Possible that there's one for the coupe and one for the convertible?)

Is there another antenna adapter that will work? Again, the Scosche VWA3B does not fit.

Thanks in advance!

Hmm, the euro antenna adapter worked just fine in my 05 roadster when I installed an aftermarket head unit.

 

Thanks MrMiata, that's the one I'll purchase next.

MoparFreak - did you have navigation in your stock head unit before switching?

 

Worked fine in my coupe.. and wife's roadster.. non nav units.. but I did notice those have there own antenna and connection for the gps.. and I've not seen anything posted about special antenna wire - adapter for going to a nav unit.

HMMM.. throw on the brakes here.. Just plugged in a Crossfire with factory nav unit on crutchfields.. and this puppy popped up as needed item..

Ok, thanks for checking that out for me, MrMiata! I'm going to Best Buy later to see if that Metra part works by itself, but if not, I'll be purchasing that adapter you linked to. Appreciate the help!

 

Just a heads up for anyone else who comes across this issue when installing an aftermarket stereo into a Crossfire that had a factory navigation unit: I went down to a car audio place (Audio Lab in Lake Forest for those of you in Orange County), and they gave me a Raptor AD-VW1 antenna adapter. It fit perfectly and my new head unit works great.

I Googled the adapter and it looks like it might be discontinued, but I thought I'd throw the information out there in case someone searches for this issue in the future.
