This is a good satellite radio that is a great satellite radio with a few additions. The radio itself has a full color display, can store up to 20 preset channels, and can rewind and replay live satellite radio. The radio can be played through an existing radio using an AUX cable or by using the built-in FM transmitter. I play mine using the built-in FM transmitter which works flawlessly once you locate an unused FM frequency. I leave the car mount in my car and remove the satellite radio and store it and a remote control in a No Snooping Allowed Faraday Bag (2 Pack), RFID Signal Blocking Bag Shielding Pouch Wallet Case (sold on Amazon) when not in use.The Onyx comes a car installation kit, however I purchased a different mount than the self-adhesive mount included in the kit. I opted for a Low Profile Drinks Cup Holder Mount for Sirius XM Onyx Plus from Charger City sold on Amazon. It provides a really good grip in any cup holder and securely holds the Sirius XM Onyx in place.The installation instructions for the Onyx Plus recommends mounting the antenna outside the vehicle. Unless you are a professional installer, most people are not up to the task or thrilled about routing the antenna wire through moulding and weatherstripping in order to mount the antenna outside the vehicle. Not that I couldn’t do it, but my biggest concern is the antenna getting damaged or tampered with and having to go through the whole installation process again. The Car Windshield Suction Cup Antenna Mount for Sirius / XM Radio from MFX2 sold on Amazon is a great alternative which provides a neat and professional looking way to mount the antenna inside your vehicle. The suction cup on this antenna mount provides a strong hold and the magnetic strips included with the mount do a great job holding the antenna in place. In most areas I get full signal strength, including the rural area in which I live. I recently traveled from Virginia to the U.P. of Michigan and back and had excellent reception most of the trip.I also bought a SXIR2 Universal Remote Control fit for SiriusXM Onyx Plus from PERFASCIN sold on Amazon. The remote works perfectly with Onyx Plus.The Onyx Plus is a nice package for anyone looking to add satellite radio to an existing vehicle or for anyone wanting to be able to move the radio from one vehicle to another. I recommend another vehicle mounting kit, a cup mount, and windshield antenna mount if you plan to move the radio from one vehicle to another. Sirius offers several introductory priced subscription packages and also offers a student and military discount.
