Audio System Enhancement Options?
Anyone know of any options on upgrading the SQ without replacing the factory head unit or making any modifications to the car? At most, I'd have no problem with replacing all the factory speakers and the factory amplifier as long as it doesn't require any significant modifications to the vehicle itself.




Can anyone help?

HUGE improvement, now it sounds like it should
Looking to replace all the speakers with Focal speakers and run them with some oldschool soundstream amps I have.
At Minimum you need the Comand NTG 2.5 Headunit which includes bluetooth support for the phone, linguatronic, a 6 disc CD/DCD Changer, SD card reader for MP3 files and a MUCH Better navigation system. The Harmon Kardon Amp and subwoofer amp. You will also need a conversion wiring harness.
If you want to go all out and do it totally right you will want to add the Sat radio receiver which also get's you live traffic updates and HD FM and AM radio, and The UCI iPod interface and the Media Interface Plus (Streaming music via bluetooth off the iPhone so you never take the phone out of your pocket and Pandora Support) and an Antenna amp (There is some additional wiring that has to be done mainly an antenna lead has to be added and routed.)
In the end you remove the Old Comand, 6 disk changer, Audio Gateway, any bluetooth puck, iPod interface, sat radio receiver, cell phone/onstar/sos box, Nav processor and old antenna amp. All of that has to come out since those components are not compatible with the NTG 2.5 system. The speakers are very very good and they stay (Including the sub) as does all their wiring and crossovers. You will be able to resell everything but the CTEL and Antenna amp for just under $2K to offset the purchase price of everything else needed.
There is some star coding that needs to be done and that get's tricky (The amp needs to be told that it's in an e-class for the proper EQ Curve to be applied)
is it worth it? Hell yes

I just got my car back from respected audio shop and now my keyless start doesn't work. I had amps and focal speakers installed.
The dash says " key not recognized"
I've tried everything to fix
