I am about to order the D3 and I am trying to order parts that I need to install..... I have an 07 Ram with the factory Sirius...will my factory antenna plug in to the Sirius box for the D3? If not is there an adapter? I already ordered the dash for the dbl din from my dealer and the peripheral harness adapter...any other recomendations besides the D3 and the sirius box to complete my install?

you can use the factory antenna. you just have to remove the plastic case on the connector end

ok can anyone tell me where to find the Sirius box thats installed in my truck?

I did one in an 06 or 07 and it was behind the glove box.

I second the behind the glove-box location.

The plastic piece is easy to remove...just go slow and look at it for a couple of minutes. It pops off.

behind glove box, you can put a zip tie on the end off the plug to keep it tight.

I had a 03 Dodge Ram with Sirius. I think the tuner is under the dash to the left of the steering wheel. That's the way I remember it.
