This modification is not for everyone. This is hidden feature so Kenwood hides this by purpose. This is risky procedure. The rules are: You have to write specific command in order to change the welcome screen. Any discrepancies will lead to error Make sure to use picture with 800 x 480 resolution in BMP 16-bit format and RGB565 setting. You can use Photoshop or Pixelformer to change your setting. Any discrepancies will result error object/picture. If you don't know anything about those information above, get help from someone with computer knowledge. I tried this modification with 2015 product. I cannot guarantee these steps are working with other types. There are many difference procedures for other type, other UI, other year and other series. This method is not for all Kenwood!! If you insist to try with different type of Kenwood and having trouble, please and please....tell me everything about your: Type of Kenwood flash drive format of flash drive type of your pic file chronology Without any information and chronology, don't expect me to understand everything. I can't read people's mind. Disclaimer: I'm not responsible for your lack of knowledge. Work at your own risk. For more info, visit our web: https://redlancerex.wordpress.com/201...
