About 6 months ago a purchased a used '04 Mazda 3. I've had an XM Skyfi for years, it my old 1990 Mazda 626, however it doesn't really fit well in the newer 3. Now that XM and Sirius are essentially the same thing, I've been thinking about getting rid of the Skyfi and going with a new OEM head unit with Sirius. There are a number of things that I'm not sure about though. Any help would be greatly appreciated!!

1) What newer OEM head units will fit in an '04 M3? There appear to be some decent deals on ebay for 06-07 head units, but I don't know if they'll work.
2) Is there any info anywhere on what I'd need to be aware of for handling any anti-theft mechanism in the radio. I'd seem mention, but nothing specific, and I'd hate to get stuck with a head unit that won't work.
3) What additional hardware is necessary to integrate Sirius to the OEM head unit? The XM tuners and adapters are fairly inexpensive, but from what I've found so far, the Sirius hardware is fairly expensive.
4) Do the newer head units have an aux out port for MP3 players etc, or do they still require something like the AuxMod Basic from http://www.sylfex.com?
5) What does everyone else prefer? Would I be better off just replacing the head unit with an aftermarket system? I'd like to keep OEM appearance, but depending on the cost of all the components, I might just choose to replace the whole head unit.

Thanks!!

1) Only '05 is a direct replacement. A '06-'08 (not '08.5) will work, but you'll have to manually splice the LCD into the HU's harness
2) No anti-theft (i.e. a code you have to input when removing the stereo)
3) In addition to a HU with the SAT button you need the sirius receiver/wiring/antenna. That comes in a kit.
4) The ACI isn't integrated to the HU, rather it plugs into the stereo. If you just want a simple input you'd be better off going with an AuxMod or a grom unit.
5) To each his own. Compared to many aftermarket HU's, and stand alone SAT units the OEM one isn't all that great, esp. since it doesn't auto-scroll the text info. From Mazda the sirius kit is ~$300, though you can usually find them on ebay for around $150.

Thanks for the input! It definitely helps. I'm still on the fence with what I'd like to do. Sounds like I'm looking at about $400. Then of course there's the complete opposite direction... I was looking at the Kenwood DNX8120 today. Now that's sweet! 3 times the cost, but it has the cool touch screen interface, aux inputs, usb, bluetooth, nav, etc. I would need an XM tuner, but that's cheaper then the Sirius tuner, and I can keep my current subscription. Maybe I'll hold of on the decision until tax time and see if Uncle Sam is willing to send any money back my way.

Thanks again!
