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

All the 2x5W files are fully compatible with 465T.

Thanks Butter for that guidance and will not flash to JCV SG version. I'll have to go research the truckie's nuvi conversion unless you happen to links to those posts.
