PUMPKIN CAR STEREO SUPPORT CENTER

I've got a Pumpkin CN03-03101B, it happend a few times where the screen stays black but the radio plays normally.
The device could only get back by pressing the reset button.

Is there any firmware update to fix this?

The firmware currently installed is:
sofia3gr_car_userdebug 5.1.1 LMY49F eng.hct.20170622.150533 test-keys
MTCD_LM_V2.52_1

Is there an update available for this device?

Hi Jammy,

sadly I discovered another issue. Sometimes when the Radio turned on and the Radio Apps starts,
it is not possible to change to another Station also the Volume Knob doesn't respond.
The Radio stays silent.
Only a short press of the Reset-Button brings it back again.

Hi,
you can flash this firmware.

Hi Jammy,

thanks for your reply. I already updated the device and will test it.
Would you also recommend an update of the MCU File to Version LM_V2.62 ?

Hi,
sorry that i don't suggest you update the mcu files if the unit works as it should .Because i find one of our clients flash that files and sudently suffer the cold boot problem.Hope your kind understandings.
