Grand C4 Picasso 1 2013 1.6 Aut.
VIN code VF7UA9HR8DJ649924
WLSI 1CZ7 WLSI 1CZ7 eMy way

My "eMy way" device keeps rebooting so I want to replace the internal micro SD card.
What software should I install?

I have read that newer firmware causes problems with the phone, and steering wheel buttons, association.

The car's info system, BT phone and radio/MP3 are important to me. I have no plans to update the GPS map
I use another Android device for GPS, live OBD2 and rear camera.

Thanks in advance for guidance

The latest firmware for "eMyWay" is 2.86. Which version is better for you? Depending on which one is now installed. If you have a version below 2.70, calibration is needed for the Bluetooth echo problem on calling. For steering wheel buttons mixed up, if you can make a backup of your settings ("user_date" directory) from the µSD card, you can copy them on the new card, if you encounter some problems.

I'm pretty sure nothing has been updated since 2013 when the car was new
