Main reason I'm staying away is that the sound quality will be compromised. As you would know, I've upgraded the speakers and with a bit of sound proofing, it sounds real good - even though I have the standard 120W 4 speaker sound system rather than the premium 180W 8 speaker one.
One of my friends' CL had an Android system and it's a worthwhile upgrade, but not for me. I hardly fiddle with Turbo's system too. Have installed a rear cam and a simple screen plastered over CL's rear view mirror for the cam and that's all I need. Haroon Radio here (from where I upgraded my speakers) has Android system available and they offered it to me, but admitted that sound quality might be compromised.
