How to update RNS510 map v17 via SD card

We download the mapstool program from https://mega.nz/file/qpQmnYxK#rKiewky... When the build is complete, you will find in the destination the following folders and files: 1.MAPS (folder) 2.MAPSDVD (folder) 3.test.mp3 (file) 4.sd_to_hdd_fw.iso (file) 5.help.html (file) Copy the [1], [2] and [3] folders and files to the SD card, then insert a blank CD-R and burn the sd_to_hdd_fw.iso ISO using the slowest burn speed available. 7. Load the new maps using SD card and custom CD loader On the RNS-510 unit of your car (engine is OFF, key is NOT in ignition): Power on the unit and insert the SD card into it. Make sure you can hear the short test.mp3 played (that means the SD card is OK) Restart the unit in Software Upgrade Mode by pressing SETUP + EJECT + MIC (INFO) buttons Wait 20 seconds and insert the firmware CD-R you burnt earlier (sd_to_hdd_fw.iso) The unit will restart and will display a message about the upgrade/copy process. Confirm upgrade and wait. The unit will start to copy the maps from SD card to the HDD. Usually this takes ~30 mins. The copy process displays 31% complete all the time, so don’t panic, just wait ~30 mins When the copy is complete, the unit will restart and display a success message. After that, it will eject the firmware DVD and the new maps will be available on your unit Afterwards, I went into the hidden menu (press setup for 20 seconds) See more things in my FB group www.facebook.com/groups/VWtiguanGreece/
