Hello.
I use igo nextgen (iGO_PAL_9.18.27.719974_SendSMS_ExtApp.apk) on my car, carlinkit tbox android tablet. I am very pleased.
I am looking for answers to the following questions. I would be glad if you help.

1- I want to remove the orange circle image.
2- I want to use 3 different map versions (Basarsoft, here, tomtom) with the Mapchanger application.
3- How to edit sys.txt to receive navigation voice over continuously via Bluetooth system.
