I suggest you follow the steps described in [Only registered and activated users can see links. ] ensuring that you substitute appropriately for 35xx (name the folder containing update.txt and ldr.bin as 1258 to match 35xx HWID and be sure to use the ldr.bin from the 35xx firmware). In the modified 140.bin you can check every feature EXCEPT ecoRoute HD and ecoRoute Purchase. If you get stuck post again with a request for it and i'll make the kit for you. Note if you have a senior model 3590 that the only available extras will be Video Player and MP3 Player.
