How do G8832 GAC and Camry Navigation Upgrade the Latest System?

Haha, buddy, if you want to save money, don't think that you are the only one who has thought of it. Do you think Japanese people are vegetarians?

This is a good monopoly opportunity. I am the only one who has the original navigation. Of course, only I can upgrade, and the price can be arbitrary. Look outside, how can you let go and do it outside? Why share the money you can earn? Do you want to do it yourself? Do you have the original map package?

A navigation CD from the original factory costs more than 1000, which is a fucking robbery.
