I used 1091.rgn file on NUVI 245W S2 V5 2G (European version with HWID 1091) Board & it enabled TTS on this unit.
Please use files accordingly to your HWID, to enable TTS (US Versions allready have TTS enabled) on these units.

Hello, I've just followed the guide to turn my UK 255w into a a TTS unit, I now have the Chinese boot logo but I only have one voice (US english-american jack tts) I've run webupdater which updated jack and a couple of others but none of the british voices show up ?

I'd forgot to move to the next stage (malay firmware) I've now done this and have all the tts voices (wahoooooo) but i have a couple of questions, does lane assist & jcv work now ? and do i need to keep my location as Singapore for them to work, or can i change it to UK ? cheers !

Lane assist working and i think jcv is as well ? (grey area pops up on lefthand side with info) ever since buying the 255 and finding they'd removed TTS from the uk/euro versions I've been a bit fecked off with it, so I'm very very pleased that everything now works ! many thanks.

A concise little tute. Thank you. I have lane assist as well but don't know if jcv is working yet.
