The best solution for me was a quality single DIN radio receiver, integrated with the PAC ROEM-.VET1 interface, a SiriusXM SVX300 Tuner and installed with the Metra 99-3300 Dash Kit Metra 99-3300 Dash Kit . All components were purchased/shipped quickly on Amazon.I selected a quality single DIN receiver newly released from Kenwood, the KDC-X705. This unit features AM/FM, HD radio, CD, Bluetooth, Handsfree Calling, USB, SiriusXM tuner ready, Alexa, plus smart phone app remote control, and 22 Wats RMS per channel x 4.When installed, the Kenwood output harness speaker wires mate for wire to the ROEM-VET1 input harness. Note the exception is the Blue/White wire on the Kenwood harness is connected to the Blue wire on the ROEM-VET1 input harness. I cut off the White/Red, Green/ Red, Gray/Red, Purple/Red and Orange wires from the ROEM-VET1 input harness at the plug because they do not connect to anything. After mating the Kenwood output harness to the ROEM-VET1 input harness, there is a long red switched 12 VDC power lead. The radio with must be connected to a switched 12 VDC power source. On 2003 and older there is a yellow wire taped to the framework in the upper left area of the passenger footwell, that is accessed by removing the footwell panel. This wire is feeds off of fuse 11 and is not utilized by anything else. This yellow wire is connected to the long red radio power lead.I found that a small raised area on a bracket that supported the pin on the back of the factory Bose radio that obstructed fitting the new radio into the dash. I cut off this raised portion off, making this bracket straight across.At this point the the large plug on the factory harness plugs into the socket on the ROEM input harness, which then is plugged into the 18-pin socket it into the ROEM-VET1 Interface module, Remember to plug in the second large plug the on the factory harness into the mating socket on the ROEM- VET1 output harness (it powers the OEM subwoofer amps), which then is plugged into the 16-pin socket on the interface module. The third small plug on the factory harness is not utilized.Follow the Kenwood, SiriusXM Tuner and Metra instructions to mount the radio to the dash. Plug in antenna with a Metra 40-GM10 antenna adapter, SiriusXM Tuner (after mounting the satellite antenna), telephone mic (after mounting mic in desired location) and the Kenwood cable into the receivers' socket. The factory look is maintained while adding 2024 conductivity and actually improving the sound quality of the factory speaker system.
