What are the advantages and disadvantages of RAV4 original navigation and Feige navigation?

The original navigation mentioned in the 4S shop is an all-in-one machine. They use the most rubbish brand and give you the most expensive price. It is best to install it in the decoration shop outside. My car is installed outside, and I charge 65,438+00,000 in the 4S shop. Damn it, I went to the decoration shop and asked for the best, only over 3 thousand. I was at Fengyuan Road 105, Wenzhou New Town, and my car was intelligently navigated.
