The navigation display unit...

The navigation display unit on my 2002 Acura MDX is blank most of the time. Now and then it will work for a while and then quit working again. All my research on line says that this is a common problem and that the display unit needs to be replaced or repaired. However, nowhere is the root cause. I took it out and don't see any problems.

Mechanic's Assistant: Are you fixing your ZDX yourself? What have you tried so far?

It is an MDX. Yes, I checked all the wiring going from the navigation unit to the dashboard and it seems fine.

Mechanic's Assistant: Have you checked all the fuses? Do you have a wiring diagram?

It appears to be an intermittent problem with the display unit - Alpine 39810-S3V-A010-M1

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No - I just want to know if I can fix the unit (solder problem, wire connection) or if I need to replace the unit. Units are very expensive - they cost almost as much as the car is worth.

Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you

the problem is a simple internal failure of the unit itself.

this is a single non repairable part per Honda, so tech's just replace them - nobody opens them to look for bad solder, etc.

the best path forward would be to get a used replacement off ebay

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.
