Here you are: 1) Download and unzip attached file, there should be an image file : A1718274559.ISO 2) Burn this ISO file to a CD or DVD empty DISC(I use CD), use minimum speed. 3) Eject all the CD or DVD in your NTG2.5 4) Insert this DISC that you just burned into NTG2.5 5) Enter to engineering menu 6) Choose SW update Then you should be able to see the START button activated. This DISC is base on the original A1718274159 telematic DISC, I just remade it to the necessary files only. You can open the CD_INFO.CDI to check the detail firmware. ############################################################ # SW_TELEMATIK_BLUETOOTH_E53_31 0019025100-001 \HU25\092200\A001902\5100_001\; # SW_TELEMATIK_GATEWAY_HIGH_E53_31 0019025300-001 \HU25\092900\A001902\5300_001\; # SW_TELEMATIK_NAVI_HIGH_ECE_E53_4 0019025600-001 \HU25\093000\A001902\5600_001\; # SW_TELEMATIK_AVC_HIGH_ECE_USA_E53_31 0019025900-001 \HU25\092900\A001902\5900_001\; Note: Do this on your own risk, I will not take responsibility to any damage.
