Firmware upgrade pumpkin andoid 4.4

[Hans]

Hi,
Where can I find an upgrade for my pumpkin car radio:
model S07
S/N 000D18A188E5
MCU MTCB-KLD6-v2.81
Android 4.4.4_27112015

Would an upgrade solve the problem of limited space, making it impossible to install apps without first deleting other apps?

Thanks

[Hans]

I think to answer my question, the Kernal is also needed:
3.0.36+

I hope this will do for the upgrade.

Thanks

Thanks,

The order ID is 204-9664442-9976347.
It is a Pumpkin Android 4.4 Universal 2 Din In Dash Sat Nav 6.95 Inch

In general the problem is the absence of a possibility to manage the available space. At this point I cannot install anything without first deleting something else to create space. It makes comparing applications a cumbersome task and this even more, because the Google apps take a lot of space, but are untouchable, or am I not looking at the right place?

Thanks
