IS there any danger in swapping out the radio unit?

I have an 04 S4 and the radio in it is not sat ready, so i want to pop my Alpine IVA-D310 (see link) http://www.crutchfield.com/S-2Ag9d1m...x?i=500IVAD310

and get my Sirius radio back that i miss so much!!!!

The rumor mill tells me that swapping out the radio may cause electronic problems since some computer signals pass through the radio or something?

There are a ton of important electronic signals that pass through your radio, including a very powerful direct current voltage which supplies power to complimentary metal oxide semiconductor devices. When applied, the direct current voltage on a polysilicon transistor will open the current path between the source and drain once the threshold voltage has been exceeded. This action then turns on another connection. Each of these switches used in various configurations form logic operations which control the reception and decoding of frequency modulated signals and the satellite receiver circuitry which decodes the GEO satellite signals.

Enough joking around..

1st... Do not install a single din stereo in an S4, it will look ridiculous! That Alpine will look like crap in your car. Get a double din that fits nicely into the factory position, like a pioneer avic.

If you correctly wire the aftermarket radio, everything will be fine. Obviously if you make a mistake and connect power to ground or something of that nature then you can have some problems. There are several wire harness kits for our car, I believe I've heard some using the Metra kit.

There are other options for satellite, ipod etc. It depends exactly on what your goal is. You may want to try the "search" function at the top of the forum as it will give you a ton of info!

for example:

The AVIC D3 has a lot of options. Are you planning to use Bluetooth? How about XM or Sirius? Do you plan on using the Ipod functions? If so you're going to need the following:

Pioneer Bluetooth adaptor - CDBTB200
Install Harness - Metra PR0180
Trim - There are a few available but to make it look factory, a custom install is prefered.
IPOD cable - CDI200
XM Tuner (Terk) -XM Direct
OR
Sirius Tuner -SIRPNR2
Smart Digital Adaptor - Check with Crutchfield for part numbers. I think there may be an all in one Tuner/Digital Adaptor now.

Hey guys, update on this. Everything I posted above is correct except what I put about the Terk tuner. That unit will work but you will NOT get full function on an AVIC unit when using XM. In other words, none of the Preset Info or artwork for any of the stations will show. In addition if you subscribe to XM Nav Traffic (very cool feature btw), that will not work either. You must use Pioneer's tuner. Not sure about how the Terk works on Sirius but I would stay away from Terk in general.

All i wanted was a setup where i could get satellite radio with the Audi OEM antenna but an after market head unit. Did a bit of searching and i found the Alpine IVA W205 ( http://www.alpine-usa.com/US-en/prod...model=IVA-W205 )

This unit is pure sex!!! you can dock the Nav unit right into the radio so its neatly tucked away when its being used!!

Now for a question i cant seem to find an answer to anywhere.... :

Will the factory Sirius antenna come with enogh cable to go from the back roof to the head unit in the front?
