    Everything is working well but since the 2024.20.1 Tesla software update, the battery stats display (charge percentage and distance estimated range) are completely inaccurate (17% and 4300km of autonomy !!!!) when my Tesla displays a 70% charged battery with approximately 362km range.

    Can you provide a new firmware to fix this problem ? Thanks !

    El brillo es demasiado alto comparado con la pantalla principal y molesto de noche. Sería bueno opción de ajuste más bajo, es realmente molesto de noche.

    merhaba anlık tüketim verilerini görmek istiyorum .
    ekranda lastik basınç sisteminin sürekli durması çok gereksiz.
    bunun yerine anlık tüketim verisi çok daha iyi olur.
