Clarion's SIRCL2 SIRIUS package includes the SIRCL1 tuner and a roof-mount antenna, allowing you to add satellite radio programming to any Clarion SIRIUS-ready in-dash receiver. Your compatible receiver will display channel, song, and artist information, and allow you to save your favorite SIRIUS channels as presets. The roof-mount antenna in the package attaches to your vehicle's roof with its powerful magnetic base.

And if you have a CD changer connected to your receiver, don't worry; the tuner's built-in pass-through lets you keep it a part of your system. The SIRCL1 tuner is compatible with all Clarion SIRIUS-ready, changer-controlling receivers.

Note: A subscription to SIRIUS is also required. Satellite radio service is available only within the lower 48 states — not available in Hawaii or U.S. territories. Limited service is available in Alaska.

Expected more, got less

Written By Marc, Livermore, CA on Thursday, March 02, 2006

Crutchfield Customer Review (What's this?)

I got this unit to go with the Clarion VRX755VD, expecting it to have features on par or even greater than most of the "plug in play" tuners. Wow, was I wrong. The SIRCL2 doesn't even have many of the basic features found in other tuners. I have a DEI Starmate Replay in my other car, so I can use that as as a baseline. The SIRCL2 is little more than the bare minimum tuner. You'd think it would take advantage of the huge realestate provided by a 7 inch touch screen, but what you get is more along the lines of what you get from the FM tuner. Channel up and down, average presents, artist/song listings when you're on that channel, nothing more. You get no lists of channels and what's playing, no genre groups, no artist/song memo seeks. You don't even get a signal meter. If had known this was the case, I would have gotten another external tuner. Talk about disappointing. The only good thing to say about it is the great sound quality. It's much better than any external tuner I've used, even with a head unit's aux in.

Inputs and Outputs


Overview: When used with a compatible Clarion head unit, this tuner allows you to receive SIRIUS satellite radio programming in your vehicle. In addition to this tuner and antenna, you must have a subscription to SIRIUS Radio to receive SIRIUS digital satellite radio signals.

Note: Satellite radio service is available only within the continental United States. Service is not available in Alaska and Hawaii.

SIRIUS Satellite Radio: SIRIUS Satellite Radio features more than 120 channels of original programming beamed coast-to-coast, including 65 channels of commercial-free, digital-quality music, and news, talk, sports, entertainment, and children's programming.

Stand Alone Operation: The tuner has a mode switch that allows you to choose CeNET or Stand Alone operation. In CeNET mode, the tuner is controlled by a compatible Clarion head unit. In Stand Alone mode, the tuner is controlled by an optional controller (DSC920S).

Selecting Channels: The tuner allows you to select channels by number or category. Channels are organized into various program categories. You can search between the different categories and then search among the channels within each category. Some head units offer a channel scan feature and all have presets for your favorite stations.

CD Changer Pass-Through: The SIRIUS radio tuner uses the CD changer input on the Clarion head unit. If you also want to use a CD changer, there is a CD changer pass-through connection on the SIRIUS radio tuner, so they can be daisy chained together.

SIRIUS Antenna: The SIRIUS antenna has a powerful magnetic base that allows you to mount the antenna on the roof or trunk lid of your vehicle. The antenna needs to be positioned in such a way that it will be free of mechanical and line-of-sight obstructions.
