First mod to my, new to me car, replaced the stock head unit for an Eonon GA7158s. This model is specific for the B7 model and even though I have the Bose amplifier this head unit installed with no rewiring at all, just slide the old unit and slide this one in.

In my old ML320 I had installed another Eonon unit, the GA2154 and was very happy with it so it was a no brainer to get this one for my A4.

 

Looks great!

 

Were you able to maintain steering wheel controls? What did you have before? Looks really nice!

 

Sorry for the late reply....

I just had the factory radio in there, non-nav unit with S/XM radio. The Eonon 7158s has a can-bus adapter included in the kit which allows steering wheel control right out of the box with no cable or wiring mods. Also it included a harness for both the Bose and non-Bose systems.

 

looks awesome! Just got my 06 a4 a couple of days ago. Looks like something I'll do to it. Saw them on eBay for $255, not bad... How are the features on it?

 

I actually ordered mine directly from Eonon. For our A4's there are 2 models, the cheaper of the 2 has less memory and ebay only had the older, less memory version. Feature wise, basically it's an android tablet in a head unit with an amp. anything you can do on android, can be done on these units.
