How much does it cost for Buick Excelle to install an original GPS?

If you install GPS in Buick Excelle's 4S shop, the price is basically above 2000. I have been to Buick 4S in Wenzhou, and the price is between 2800 and 3500. If you install DVD navigation, the price is basically above 5000. In fact, Buick doesn't produce navigation GPS at all, but chooses things from other manufacturers. I suggest you choose an installation yourself.
