HI All  
I know this topic has been covered somewhere before in the forum, I Have read the responses and tried installing maps alone, rolling back to previous versions, removing gracenotes , nothing has worked

When I select maps on Sync3, the feature doesnt open & on the home screen, it shows maps loading, which never loads

Please assist with any advise as to how to get the maps working (I dont use it, as I use Waze or Google maps, However the fact that something isn’t working is frustrating me)

Are we supposed to guess what you tried to do?

Either way, it’s a good thing for you to read the [Basic Usage - CyanLabs](https://cyanlabs.net/docs/syn3updater/getting-started/basic-usage/) guide since it seems you didn’t install maps on a NAV unit.

If after reading that it still does not work, please provide more details other than “it does not work”, like logs and context.

Super old APIM and the AB does not even match up in this pic, way to many bits. If this is truely a J series APIM than the calibration in it is wrong also. This sounds like a retrofit, Do you have a pic of the sticker on the APIM?
