Just FYI, I bought one for my 2011 DC OR. Install went fine, but some music is overlayed by static/crackling, mostly at peaks. Tried other iphones, different music formats, streaming music, etc etc, all had the same issue. Even navigation voice from google gets crackly sometimes. Issue occurs both on the 30 pin connection and when using the AUX port on the GTA box.
No other time does the sound system have the issue (CD, radio, Aux, XM...all are completely fine)
Spoke with Maurizio and he has been very responsive and attempting to help. I returned the unit for a replacement but the exact same issue is occuring with the second one.
The only way to reduce the static noise is to:
a) use the AUX port on the GTA box and turn the phone volume WAY down. This is pointless since 1) I could juse use the AUX port on the truck and be done with it, and 2) with the phone volume so low, the head unit can't get loud enough even at max 3) AUX sounds like crap compared to 30 pin anways
b) turn Sound Check on, on the iphone Music Setting menu. Also selecting some of the EQ setting in that menu helps to further reduce the noise, but it's typically EQ choices that sound like crap, so this isn't a viable sollution. Sound Check is ok though, and helps a lot. Now I only hear the static about 20% of the time.
The other issue I'm having is that even in Playlist mode, the text (names of songs, etc) will not show up on the head unit. Only Track #.
FWIW, the model number on the front of my head unit is A518A8
Again, GTA staff has been helpful and supportive in trying to look into the issues.
