2015 GLA250 4Matic Updates
It has NTG4.5 with Audio20.
Few questions:
1) If I get software update done, will it provide any extra feature/s (Navigation, BackupCamera compatibility, Any other feature) ?
2) As its pre-owned and the warranty about to expire in few days, should I get it serviced only at MB facilities or any 3rd party ?
3) Was wondering if I can install a backup camera, my NTG4.5 HU has green fakra empty. Do I need an interface/proxy or just camera would work ? In engineering menu, I do not have any reverse camera option
