    Hi all,

    I recently installed a Pioneer AVH-W4500NEX and wanted to retain the factory GPS antenna. I ordered the idatalink ACC-SAT-TO2 from sonicelectronix and of course it had two XM adapters and no pioneer GPS adapter. Amazon was able to send me the correct wires. The connections for XM and GPS use the same connector and was wondering which is which.

    I think this is GPS:

    and this is XM because it’s in the same harness as the radio antenna (shark fin).

    Thanks in advance!

    I have an SR5, so I am pretty sure that there is no GPS wire, and my XM radio antenna looks like your picture #1.

    Side note - did that cord from Amazon fit both your XM antenna and gps antenna?

    Well crap that is confusing because I thought for sure the XM used the shark fin and the gps was behind the dash.

    light green is for pioneer gps. Black connector is for XM. But yes, the teal end fits both connectors in the vehicle.

    Okay thanks. I'm looking for the XM adapter, but I don't need the other two. Are you able to find a link for just the XM one in your photo? Or the name of the connector type if it isn't proprietary to Maestro?

    I'm 99% sure that my xm radio antenna was a white plastic connector like your photo #1 and not dark like #2. Either way though, it is an easy test. Hook it up to your XM and see if it works.

    I can probably send you mine as I have no plans on using XM since just use the app with carplay. DM me.

    I wish I had an XM box to test it. It’s unclear how the pioneer uses the gps antenna because navigation seems to work fine without it hooked up. I’m guessing it works in conjunction with the phones gps and saves battery. Maybe somebody else knows.

    Not sure, but if you are using the phone for navigation through carplay, obviously you wouldn't need the GPS antenna at all. If your head unit has built in GPS capabilities then that would use the antenna... Doubt it would help save data on your phone though.

    I'll DM you. That would be sweet, because I have an external XM receiver that I would love to use with the factory antenna!

    I’ve read on other forums that the gps traffic data and the weather function is through the HD radio so that might be why it is hooked through the “shark fin”

    I think you're correct. I remember the GPS going to the left in the dash...

    The SR5 "does" have a GPS antenna (and antenna wire) and it "is" the white connector. The XM antenna connector is the Grey.

    I just recently removed my EnTune (+) HU and installed an EnTune Premium HU (with built-in nav) in my SR5.

    Hmmm I don't remember the 2nd connector. I might have just bundled it up and dropped it down behind the dash though when I realized I didn't need it. Its possible... It has been a while.

    I don't have a picture of my new HU installed. Guess I need to take one.
