(Newb here - I've checked the newbie sticky, but didn't see any info on this topic)

My car did not come with Navigation when I bought it, so I've recently bought and installed the system. My only problem is that I do not have the stock GPS antenna. I've been told that any antenna will work as long as it has the correct connector. Is this accurate?

Here's a link to my cardomain page so you can see what I'm working with.

If it would help, I can take a picture of the back of the navigation receiver. There are several unused connectors (although some of which are to connect it to the stereo for the voice guidance).

Any ideas on which type of gps antenna I should get would be a great help.

Thanks in advance!
