Is there any place in Shenzhen that can repair all-in-one DVD navigation machines?

Currently there is no one that specializes in repairing navigators. Where the navigator is installed is where it should be repaired. If it is brought with you when you buy a car, go to 4S for repair.

Because the maintenance cost of the navigator is too high-----How long will it take to disassemble the navigator? Right? And the navigator is integrated internally, so there is basically no room for maintenance. For example, are there still people who repair optical drives now? No, the repair cost is more expensive than buying a new one.
