Hello cr08,
Couple of questions.
I did the upgrade to SYNC3 with APIM from ebay which had 3.2 installed.
I upgrade to 3.4 via Synalab sync3 updater but display was defaulted to 50% was unable to change it within Sync menu.
Did you had any issues with the display brightness? I downgraded to 3.3 and display was OK.
Also, I have not programmed the APIM yet with new asbuilt file. Few issues but nothing major.
Did you update the APIM module only? Since my car is 2014 Energi SEL with 300A, do I just down load the .ab file with 2016 VIN number that has same 300A option?
Thanks much in advance.
