PUMPKIN CAR STEREO SUPPORT CENTER

Hi,

I recently bought a player for BMW Model 11-RQ1129E-ES on amazon.es

( https://www.amazon.es/gp/product/B01GYH ... UTF8&psc=1
Order number: 402-2564076-7686747 )

All functions of the device work properly, but I have two problems after the car to turn off for a while:

- The system time is lost.
- Radio stations tuned lost

How can I fix the problem?


Thank you

Hi,
Sorry for the late reply due to the National Day.
Regarding the issue you described, sorry about this, cause I had got the feedback from one of another clients who had the same problem as you.
After discussing this problem with the factory technician, they first thought it can be solved by the update mcu version, but unfortunately, the solution can be only operated at their side, even our side could not use the mcu version to solve this problem.
But they provided us another solution which seems to be a little difficult, to replace the old main board can solve the problem.
It's not a good solution for our clients, I understand, so if you don't want, you can return it back to us and get a full refund.
Or you just need to wait for a week to get a new main board to solve the problem, and we can send you the reference video to dismantle the unit and replace the main board.
Really sorry for the trouble brought to you again.
Best regards

Thanks for the response Jammy,

I sent now an email to your colleague Felipe Wen, about how we can proceed to replace the plate myself, to avoid me running out of radio, I'm engineer, I have training for do it.
What information do you need to send me the new motherboard? I send you my postal address on a private message?

Regards,
Domenec

Hi,
