how do I repair the navigation screen on my 2010 yukon xl denali
The navigation screen on my 2010 Yukon Denali is now black. The radio and other features still work but the screen is black. At first, the GMC logo would appear intermittently but now nothing at all.
You don't. It's more cost effective to replace the whole unit, sorry to say. Look online like eBay or Craigslist for a replacement.
