first of all this is an amazing forum.  kudos to all of you

 

my mothers 2015 yukon.  she ordered the maps update, and it stays on zero %.

 

sounds like the emmc is bad.

 

something tells me this is basic knowledge that I cant find, but is there a way to fix this?  she took it to the dealer and they couldnt fix it.

 

she I try and reflow the solder around the emmc?  is it replacement needed?

 

thanks in advance

 

 

Easiest would be to just pick up a used one from Ebay for about $100.  It is either the 23228496 (AVF) or the 23266008 (non-AVF) in that Yukon.  There is a 1/2 year split so you need the VIN to check the RPO code for "AVF".

 

The non-2.5 HMI modules are pretty affordable.  If you don't want to upgrade to the 2.5 version.

thanks!

 

I'll probably just swap it out.  

 

would be nice to get the carplay etc, but just getting it working will be better.  

 

2.5s seem to be $300 plus all the other stuff I'd need to do apparently

 

was really hoping to repair the current one as sounds like something fried the writeable memory

Then you will need to program the used HMI with DPS, or SPS, and do the VIN learn.

unfortunately not seeing too many $100 options.  $250+
