The SIRIUS Sportster 4, Sportster 5, Starmate 4, Starmate 5, and Stratus plug-and-play radios all come with car accessories: a cradle, an antenna, and a car power adapter. This handy car kit includes another full set of car accessories, which makes it easy for you to use your SIRIUS plug-and-play radio in a second vehicle.

The radio sits snugly in the cradle, which you can secure to your windshield using the included suction-cup mount. The antenna attaches to your roof with its magnetic base, while the adapter plugs right into your car's cigarette lighter or power port to provide power to the radio. Send the sound to your car stereo using your radio's built-in wireless FM transmitter*, or connect the cradle directly to your stereo's auxiliary input, if it has one, with an optional set of patch cables. SIRIUS satellite radios are sold separately.

*Important note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna. Sirius/XM includes extra wiring in order to address this issue, but Crutchfield strongly encourages customers to use an auxiliary input, wired FM modulator, or cassette adapter to ensure your satisfaction with the performance and cosmetics of the satellite radio.

SUPV1 Car Kit

Written By ivan, Tampa, FL on Monday, February 09, 2009

Crutchfield Customer Review (What's this?)

Been a good product so far, seems to be well built and put together.
Instructions were good, could be a bit more detailed on the initial
configuration and setup.
The install instructions were pretty good and very general. Nothing from
Crutchfields on my model of car.. no big deal, I am pretty handy and was
able to install and hide wires.
My only real complaint is with the Wireless 20' FM Extender Antenna, it
really doesn't work worth a darn. They really should make available a kit
with the FM Direct Adapter cable. Instead I had to make two separate
purchases with additional shipping costs.
That would be a real customer service plus to offer both options, Wired Kit
and a Wireless kit.
That is really the only reason I give it 3 stars instead of 5.

dock and play

installed dock and play sirius on my goldwing and my s10 blazer and love the old school sounds

Works fine, but not quite what I wanted

Crutchfield Customer Review (What's this?)

The installation went well and the product works fine.

I installed it in my second car. The Stratus radio came with two mount options, a vent mount and an adhesive mount that also had two screw holes. That was what I really needed for the second car. I knew when I bought the SUPV1 that it had a vent mount and a suction cup mount. I figured the suction cup mount could be adapted for screw mounting and this proved to be easy to do.

SIRIUS SUPV1 Car Kit

Crutchfield Customer Review (What's this?)

I had the SIRIUS professionally installed since Sirius sent me free install cards. I just upgraded from the Sportster Replay to the new Sportster 5. I had to buy an extra kit for my second vehicle. Everything works fine & looks great. I had to get the FM modulator for my first car but used the auxiliary input jack on my second vehicle. Everything works flawlessly. I've used it for about a month now.

Picked Up Two!

This Docking Station hasn't work from day 1. Still working with Sirius to get a new one (I guess). I thought it was just the power plug so I bought a hard wire kit. Sill nothing. Something in the docking station is bad. I would'nt recommend this product to anyone

Product Research

Features:

Overview: The SUPV1 car kit includes everything you need to install the Sirius Sportster (item number 607SP4TK1 or 607SP5TK1), the Starmate Replay (item number 607ST4), or the Stratus (item number 607SV3 or 607SV4TK1) in your vehicle. The kit is compatible with the SP4, SP4R, SP3 and SP3B SIRIUS brand Plug & Play receivers, and it contains a docking cradle, mounting bracket, DC power cigarette lighter adapter, roof-mount antenna, FM extender antenna and mounting hardware. The Sirius receiver (sold separately) mounts firmly in the cradle, where antenna, power and signal connections are made.

Docking Station: Compatible Plug & Play receivers plug into the docking cradle and lock into place. The docking station mounts to the supplied mounting brackets using 4 machine screws. On the back of the dock, there are inputs for the antenna and DC power supply, a line output jack (3.5mm stereo mini-jack), a transmission antenna output and a locking switch.

Note: The locking switch is used to attach the cradle adapter to the dock which allows ST or SV Sirius Plug and Play receiver models to work with the SUPV1 car docking station.

Antenna: The low-profile 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. The antenna' s dimensions are: Diameter = 2.221", H = 0.495", Cable Length = 21'.

Note: The attached micro cable has a single SMB connector, which plugs into the cradle.

FM Extender Antenna: The FM Extender Antenna is provided to maximize the audio quality of your Sirius radio when using the built-in FM transmitter in your Sirius tuner to transmit the audio to your vehicle's FM radio. The FM Extender Antenna should be placed inside the vehicle in close proximity to the your vehicle's factory FM antenna. The FM Extender Antenna has permanent adhesive mounts for installing it along your vehicle's window. The Antenna portion measures 18" long and utilizes an attached 18.5' cord to route the antenna through your vehicle. The cord has a right angle mini-jack connector on the end of it that plugs into the FM-Out on back of the car docking station.

Important Note from Crutchfield: Current FCC rules limit the transmission strength of wireless FM transmitters to a point where transmission needs to take place very near your FM antenna. Sirius includes extra wiring in order to address this issue, but Crutchfield strongly encourages customers to use an auxiliary input, wired FM modulator, or cassette adapter to ensure satisfaction with the performance and cosmetics of this satellite radio.

Mounting Bases:

  • Suction Cup Mount: The suction cup mount may be attached to any smooth surface. The mount has an adjustable arm to position the dock which then can be locked into place.
  • Vent Mount: This mount attaches to your vehicle's air vents

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

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

Optional Pro-Fit Brackets: The SUPV1 car kit can be used with many of the Pro-Fit Vehicle-Specific Mounts (VSMs) to provide a custom mount for your vehicle. Please check the Crutchfield Vehicle Selector for compatibility with your vehicle.
