PACROEM-VET1 System Interface Kit (Replace Factory Radio for Corvette Vehicles)

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.

Easy install, worked to fit an Alpine deck in a C5 (02) Corvette. Have had 0 issues 3 months later with the new Alpine deck using Bluetooth, Android auto, and other features. Would reccomend.

This works amazingly well! But beware your wiring!The blue/white wire from your head unit connects to the BLUE wire on the PAC harnes.You will need to adjust the pots. Just past halfway is perfect!Totally satisfied!

Installed on a 2003 Z06 it allowed me to keep the factory BOSE system for now, install wasn't terrible but the instructions were lack luster. Lots of pins in the harness don't go anywhere which is fine but awkward when you realize after the install (things like the illumination wire and power antenna wire). It's fine that those aren't there but some documentation instead of a random wire to nowhere would be nice.It's also quite bulky but not impossible.

I had it installed at Beat Buy and they stated it was easy to install.

I used this to install a Kenwood KDC-X704 in my 03 Z06. It was easier than i thought just match up the wires as it says in the directions, then plug everything in. Sounds better than the stock headunit. I played with the sound adjusters for the front speakers and found that the best sound balance is to set the little screw arrow things to aim at about the 12:30 hour position (all the way down and then back a bit).

There were no clear directions on my radio to use it. No clear directions on utube either had to have a professional install it for me then why buy it.

Works fairly well, but as many Corvette blogs have noted, you must adjust the potentiometers on the PAC ROEMVET-1 to get more high frequencies from the front door speakers.The instructions that come with the unit could use more diagrams and instead rely on written explanations. After removing the stock head unit (HU), you will have 3 cables - a large 20-pin connector (C1 & C2), a 4-pin connector (C3) and a 9-pin connector (C4). C1+C2 connects to a wiring harness that comes with the ROEMVET-1; this harness connects to your new HU and also to the ROEMVET-1. C3 is not used. C4 is connected to the ROEMVET-1 via another wiring harness. I had mistakenly left the C4 -> ROEMVET-1 connection off and had no bass.
