I purchased the iSimple ISNI531 and after installing I noticed that although it was cd quality the OEM radio volume was missing. Basically when using the AUX although the volume was on full at 31 it sounded as if it was playing at 21 compared to the radio volume. After contacting isimple I was told that was "normal" that it wasn't as pound so long story short I'm return it.

Now for clarification purposes I have a 2005 NONE BOSE system.
If I am installing a dd I would need the following correct:

A metra 99-7605a DD bezel or JDM.

Keeping Bose Amp in RED and ALL other applications in BLUE, required for both in BLACK:
1. Metra 40-NI10 - AM/FM Antenna adapter.
2. Steering Wheel Interface- Metra Axxess ASWC-1 (Do I need this?)
3. Metra 70-7550 (Non-Bose) Wiring Harness. (Amazon is saying this doesnt work for my 2005 Non Bose)


Can someone confirm this is correct for a Non Bose car? I haven't picked out a radio yet but know I want a touch screen under $300.

Thank you

Well you got to the DDin install page, which is nice. You want all the things in red as stated in the thread. JDM controller is going to be expensive but looks 900x better.

As for the radio, touch screens are overrated so I would just get one with big buttons that are easy to find when driving.

Ok so I need the steering wheel controller no bypassing that, and is there other harnesses to get or that is the one I HAVE TO get?

Well, you can go with what amazon says or what's been tested and confirmed by hundreds of G35 owners.

The list is the go-to-list for a reason. Buy what's on it.
