Thread: An updated guide to enable JCV, Highway Mode, Lane assist & TTS on 2x5w

I just got the 255WT, with HWID 0827 and P/N A0104-XX. Just for fun, i was trying to convert it with Flash_Kit_0827_Hybrid_RGN but it ended up with soft brick, hanging by Garmin logo forever. After turning it off (sliding pw button 10 seconds) i managed to restore it with Flash_Kit_0827_RGN. I tried 3 times, with the same result, then i gave up. Seems like 575-A0104-XX versions cannot be converted into Nüvi 465... I tried to flash it to SG version which went OK, lane assist and Junction view does work, but there are problems with EU language files. Some of the files aren't displayed correctly, and voice files basically don't exist for the SG version, expect the English. I would need some western EU voice files, like Slovakian, Hunagrian, Czech... But i could not find them... So i ended up converting it back to original state, sadly no conversion is fully compatible with this unit...
