Apparently elantra models outside PK have driver profile where seat settings are saved. Was wondering that maybe this feature is also available in PK version and not accessible due to the android unit that PK version uses, or maybe stored in ecu and can be accessed using a device like elm327 (not sure what works with it, used this with my Honda), provided that the required hardware or sensors are already there. Just a long shot 
Secondly, where is elantra ecu port and what device I can connect (like OBD2 elm327) I can use ?
Just found out about https://myhyundaipakistan.com/
Does anyone know about it, it says it is for elantra cars Pakistan.
