Updated from 3.0.19205 to 3.4.23188 and everything works fine except for the fact that when I go to the Nav screen it just is black except for the menu bar with the clock

The system works fine but NAV will not load. Vehicle was a 2014 SYNC 2, but I updated hardware to a 2018 APIM and a 2019 screen. When I loaded in it was running 3.0 just fine, Nav worked, but I decided to update maps and SYNC to 3.4 because I like the latest and greatest. Now despite a reinstall I just can’t get the NAV screen to display anything but black, android auto works fine though and GPS seems to work. I had a fault with my original GPS antenna but I just replaced it and its clear now, still have the same black screen. No vehicle position, no maps, just the white menu bar on the top. I can hit the home button and it works, so its not freezing or anything.

So this is clearly a retrofit since no 2014 came with Sync 3. Where did you get this APIM? Usually ones that have a problem like this when you update it are Chinese knockoff APIM’s. Would you happen to have a pic of the back sticker of the APIM?

3

It’s a junkyard sourced unit and I would have to take it apart to show the back but it definitely looked like an OEM unit.

4

Probably OEM than. Do you know if it is an H series?

If I understand what you were asking correctly I believe its a J series.

8

Yea that’s a legit J series. Should be a good APIM.

9

Yeah I don’t know what I’m doing wrong

10

Did you do a master reset after the upload to the car?

Often you get nav issues unless you do that.

11

I’d drop the build to 3.4.21265
Its not all that unusual for older Sync2/MFT to have issues with 3.4.23188.

12

Yes I was. Downgrading to 3.4.22000 fixed it

13

3.4.22200 fixed it anyway, but I’m not running Sync 2 hardware.

14

Referring to the OTHER modules in your car, the Sync2/MFT OS is a fork of Windows CE 6.5, Sync 3 OS is Blackberry QNX Auto.
3.4.22200 is a buggy release, see all the associated threads about the RW data partition filling up due to a bug introduced after 3.4.21265.
The “clean” releases are 3.4.23188 & 3.4.21265, with 3.4.21265 being required for some older vehicles due to module firmware incompatibility issues.

15

Sweet I’ll tweak it to 21265 then. Thanks!
