Question: The retail package at Best Buy comes with the first three months of service and All Access for free.  Is this the same deal here?
Document: I am already an XM subscriber and just wanted to add this as an additional radio. When I logged onto the website, it would only let me choose the &#34;three free month&#34; promotion, which required a minimum of 6-months of the most expensive premium service. If you did not complete the 6-months, they would charge you $75.
In my car, I was able to hide it behind the head unit in the dash. The old Sirius clunker was stashed inside my center console because it was so huge. Big improvement! When you first turn it on, the tuner automatically starts a &#34;courtesy activation&#34; period that gives you full, free access to the SXM service for about 5 days.
Bought this tuner to add on to a new deck install. This was the first time I had installed this item. It came with easy to follow install directions, and setting up the subscription was a no brainer (except Sirius wanted me to buy their top of the line package, and I had to sleuth around the site to change it to a lower package) . Antenna has magnet mounting and ample length of cord that's tiny enough to easily hide within your car's interior.
I have a very nice stereo system in my car. While listening to music through aux, usb, bluetooth, DVD, or regular radio broadcasting the sound quality is superior. A few months ago when sirius had the free two weeks of programming i thought i would buy this and test it out. To my surprise the tuner really does a bad job at converting the radio waves to quality sound. It was to the point where i just couldn't listen to it anymore (because i am an audiophile).
I wanted Sirius this is XM but it will do its already installed I though there was to be 3 months free service with this but XM says no
For the guy that wants to put XM radio in their car and can install their own stereo this will be a necessary install. This will go under the dash and attach to your SirusXM connect ready device. So long story made short; buy a deck that is SirusXM connect ready, Buy the SirusXM connect tuner box,  put both in the dash,  connect them and the SirusXM antenna that comes with the connect box. Subscribe to a SirusXM service and your done. Took me under an hour.
If you unhook the factory xm antenna from the factory xm receiver behind the glovebox, you can simply slice off the plastic sleeve on the antenna cable and plug it into the SiriusXM receiver.The trial period is too short. 5 days or so.Right now you get 3 free months...if you pay for 6 months of premium service.
If you want a non stop run around from India then have a blast! they will not allow you to purchase the 14.49 per month plan on the sirrus website. they will only let you sign up for the free 3 month trial that isn't free if you read into it so you are forced to deal with the customer service in India. I am going on 2 hours with them and I'm all signed up and being charged but still no signal.
I bought a new Kenwood radio and had the V200 installed with it. I thought I had three months to try it out before having to pay for it. I was looking forward to trying it over Thanksgiving and Christmas. Boy was I wrong! You only get 5 days to try it from the time it was installed.
I replaced my factory GM stereo and bought a XM ready stereo. I had to buy a adapter for 10 dollars to use my original antenna on my vehicle so I didn't have to use the magnetic stick on antenna that comes with this. Easy install and the reception is better than the original XM radio that came with the vehicle.
Answer: Yes, deal is from Sirius XM.    Currently enjoying my free 3 months, you will have to agree to get first 3 months free and pay for next 3.
