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?
