XM Radio Hacked by Car Computer Hobbyists 189

Posted by michael from the i-want-my-mtv dept.
An anonymous reader writes "There is an article over at News.com that talks about a small Florida company called Hybrid Mobile Solutions, that hacked XM Radio. They created a cable and software that makes the new XM Commander and XM Direct units work just like an XMPCR. They are in negotiations with TimeTrax to allow recording of XM Radio to MP3's. XMPCR was canned due to this late last month."

      It's the personal computer receiver for XM satellite radio. XM used to sell it but discontinued it when the TimeTrax software came out that allowed the XMPCR user to record music from the XMPCR hardware. The RIAA was apparently behind that action.

      Here [xmradio.com] is the official definition of what it is, picture and all.

      Basically, XM canned this because people were recording the stream and distributing it over the web. Since XM is a premium service, they didn't want their shows being disseminated over the web so they have cancelled this product and will most likely create something new that is less easy to record from, although I'm sure it won't be impossible for the 1337 hackers out there.

      the XMPCR is a little box that allows you to listen to XM radio on your pc/mac/sun (mac/sun supported by 3rd party apps). it's a little box that has an audio out which you simply plug in to your mic or line-in. it's controlled via usb (the unit internally has a usb->serial adapter which happens to be well supported by *bsd, linux, etc).

      the protocol that goes over the usb cable (used to change channels, etc) was reverse engineered, and people started making all sorts of applications to play with them. timetrax is one that allows you to record the music, as well as automatically add the title, artist, etc info to the ripped song

      XMPCR is the XM PC Receiver for XM Satellite Radio. It is a USB device which connects to a Windows PC (with the included software, but there are Linux, Macintosh and Perl versions). It streams XM radio into your sound card and makes it extremely easy to record. It provide artist and title with each track so that you can even record songs and label them with the appropriate artist and title automatically.

      Of course, we are just speaking hypothetically. :-) These were being offered for $50 dollars until about one month ago, when XM discontinued them. Since then, many folks have been trying to find a way to produce XMPCRs.

      For a little more info (and a photo), check out the XMFan Store [xmfanstore.com]. They are now very difficult (or expensive) to find. Personally, I don't know that I could be talked into selling mine!

    Their website does not have a whole lot of information though the XM product is their along with the $45 price and a shopping cart that allows you to order. What the site does not tell you is how this works with an existing XM account. For example, I have a subscription and a Roady I reciever. Would I be able to use the PC product and still use my Roady or does entering the subscription/radio code into the PC product "turn off" the Roady? XM charges an addtional $6.99 per month per device for up to four addtional receivers. Still, I'd pay the extra money to have the PC product. In my case it's not for recording as much as to be able to stream the music easily throughout my house. They also do not provide any software themselves right now though their website indicates they are working on developing a relationship with TimeTrax that I assume will allow them to bundle the software with their hardware. I think this would be a very popular offering. I wonder how long it will take before XM Radio or the RIAA gets a cease an desist order from a judge.

      There was no reverse engineering of the service itself by these guys, or of the XM Tuner unit. The tuner module found in every XM unit speaks the same serial protocol as the PCR, and the PCR protocol was deciphered ages ago by dobbz, nsayer, and others from the XMFan board (and later apparently nsayer was assisted in filling in the gaps by XM themselves when they actually supported the 3rd party XMPCR development community).

      This is just a serial protocol translator, one of at least 3 or 4 separate implementations that have popped up in the last 3 or 4 weeks - a modest reverse engineering of the XMDirect's headunit protocol, translating (probably 1:1) serial commands to the internal tuner (tincan) serial format.
      • An update: at my site [hardgrok.org]. The XMDirect "protocol" is just a trivial header of 3 XM 5AA5 serial opcodes. Like I predicted, it was a trivial thing to dump with a serial monitor and figure this out (I just didn't realize quite how trivial it would be).

      Some other facts:
      • It's not been conclusively proven that the recording features of TimeTrax hastened the demise of the XM-PCR unit. In fact, IIRC, XM Radio hasn't even admitted that they've discontinued it. Many feel the PCR was on its way out regardless (which was part of why many sites were selling at steep discounts in the month or two prior to its disappearance).
      • This unit is basically just a pinout converter, maybe with level adjustment and such. The software must use the XM Direct protocol, which is different from the XM PCR protocl and has not yet been published (by anyone, even those who created this system).
      • Another system (at xmfan.com) includes a USB adaptor and a microcontroller-based protocol converter, that accepts the existing XM PCR commands and converts them to XM Direct. That system works with all existing software except the stock software distributed with XM PCR.
      What is going to happen: Someone is going to get the crap sued out of them.

      Why? They've done nothing wrong. In fact, they've done exactly what Terk/Blitzsafe is doing -- provided an interface between the XM Direct tuner module and a head unit. Only in this case the head unit is a PC, not a car radio.

    One terrific advantage of this hack will be combining XM and Sirius satellite radio receivers. Why choose between different channels in the same medium by buying one of two available boxes? It's like buying an AM or FM radio in the 1960s. Integrate two sets of HW into a device with one UI, as long as it's unified for user operations.

That's a rather expensive advantage.

So after 2 years we will have spent $700 for something that could easily have cost that much, in constant dollars, if it was even available.

    First of all, this isn't a hack of XM Radio per se, it's just a simple reverse engineering of the undocumented cable spec for the XMDirect unit. The XMDirect has an 8 pin mini-DIN pinout and an internal 32 bit Atmel which translates serial instructions between XM's undocumented "car headunit" serial format and the standard, internal "A5 5A" serial format used directly by the XMPCR units, for which there is already quite a bit of Open Source software [sarovar.org] (incidentally, PCRCommander does pretty much everything that TimeTrax does).

    This "solution" is pretty much just a cable, and this groups software which does the translation. If you want something that works with all the existing software out there now, what you really want is the DirectPCR [xmfanstore.com] brought to you by Ryan and the XMFan people [xmfan.com]. The DirectPCR is more expensive, because it's actually got a microprocessor that reverse translates the standard "A5 5A" serial commands into XM Direct format (which is then dutifully translated back by the XM Direct).


    The DirectPCR is the best solution if you really want something with the power and cool factor of the now-defunct XMPCR (no I don't have any business relationship, I'm just an XMFan regular and have been following developments). As for "hack factor" at least three separate people or groups have separately done the XMDirect protocol translation. If you have the right equipment, it's probably about an afternoon's work - just hook up two serial monitors side by side and dump away. So there isn't that much hack cred to speak of in this. Furthermore, if you're comfortable with a soldering iron, you can trivially build an XMPCR-compatible unit out of a SkyFi with a DB9 header, a MAX232, and an optical adapter board.

  • which units (if any) that are hackable can be easily converted to opto or coax spdif out?

    no way I want to pipe analog in to my 'soundcard' and then record via that. its spdif or nothing, really. its bad enough its compressed - but doing a D/A and then A/D for no good reason just reduces quality and makes this sound more like FM than a CD.

I can't see things going that far yet. But like it or not, the average person has a lot of options for recording these days.

    Back when I was in high school and was lusting after a 4 track reel-to-reel multitrack deck from Tascam, there was a financial barrier to high quality recordings. But today, there are so many options out there that even if you aren't using AES/EBU digital connection (no SCMS DRM) you can still get much higher quality copies than you could with a cassette deck back in the 80s. So, even if the RIAA and MPAA do get DRM so intertwined into newer audio and video gear, it's going to be next to impossible to prevent older decent quality devices from recording. This is a battle that can't be won without draconian mesaures.

    The shame of all of this is that nearly everyone with a computer has the facilities for making their own music and therefore bypassing the RIAA altogether. I do remember a period of time in the 80s when it was illegal to own a 4-track recorder in a residential area in my state. I wonder if they are going to try that with software based virtual studios? Likely not since most people with the ability and talent are just too lazy to make their own music. (It's easier than you think. If you can set up a Cisco network, you can make your own music.) So, what can the RIAA and MPAA do to stop people from pirating? How about they take away all sound cards and video caputre cards, digital audio and video recorders, and software based audio? They can't. The genie is out of the bottle.

    With that out of the way, is it right to distribute music that you aren't authorized to distribute? Absolutely not. Quite a problem, ehhh?
    • But like it or not, the average person has a lot of options for recording these days.

      For the moment anyway, but with the digital revolution they have the option of putting the genie back in the bottle via broadcast flags etc that the average user doesn't know about until it's too late. Digital radios requiring digital receivers that have digital connections to digital speakers...not terribly far fetched anymore.

      This is a battle that can't be won without draconian mesaures.

      • I understand what you were saying about digital recording devices. But, what I meant was that a pentium 100 with a decent soundcard with analog line in and line out would be able to easily record from any digital playback device unless they find a way to make speakers that are truly digital. Even then, you can put the speakers in boxes with mics and still record. The quality from a PC even recording with a soundblaster 16 rivals most cheap analogue cassette decks.
  • You know, a while ago I bought a PCR and was psyched when I saw the TimeTrax software so I bought it. I tested it and it works brilliantly, but honestly, I haven't really found a need to record mp3's wholesale. I mean, I have the pcr and I can go channel to channel and listen to whatever I want. I just listen to my xm and don't even use the TimeTrax software.

    I'm so happy with xm that I'm going to get a head unit in my truck too. It's only like $6/month for an additional radio if you have one already, s
  • It's sad. XM should really look how the open source mentality of making things better worked with TiVo. The would have been taken under a long time ago if they weren't hacked and made better.

    Couldn't one just take the GNUnilink package from Sourceforge/Freshmeat and combine it with the short-lived Sony XM receiver that was a Unilink module, and control it that way?

    (Unilink is Sony's protocol that allows decks to control disc changers and a limited number of other devices like TV tuners, mobile VHS VCR, DSP modules and so forth).

    XM is likely to be over in a few years anyway [space.com], right?
