PUMPKIN CAR STEREO SUPPORT CENTER

Hallo support team,
please help in the following matter:

I updated the unit with the wrong MCU update software. Now the PX5 Screen solution has changed from PX5 (800x480) to PX5 (1024x600). How can undo this change of the screen? Please help.
Here are the original data of the unit (before the update):

Hi,
Can you download the following MCU update file:
https://mega.nz/#!CD42CAZL!Xh6HXpLdUd-C ... dbR8FZxp0g
Installation method: Please do not unzip the file after downloading it. Put it into the root directory of one SD card. Insert it into the GPS slot, Click Settings-System- MCU upgrade. Cheers
Best Regards
Jammy

Dear Jammy,
I did as you told me. But I have still the wrong resolution and I can only see the left section of the screen. Nothing changed!
What can we do else?
Regards, Wolfgang

Good Morning Jammy,

Best regards
Wolfgang
