Hi can u tell which after market u have installed in ur grande.
Whats the model of ur car?
What are the specs of the HU which u have got from market?
Is it working with multimedia steering. Is sound change and track changing working with new HU
I have got new grande and the system is pathetic. After complain dealership called me and checked my system and said all of them have same specs. We can change ur HU but i refused as all of them are of same specs and the new might be worse. I am thinking to get aftermarket one.
