How do I enable TTS in Nuvi 1100 hwid 971. My main problem is to get the vpm file for Jill american english voice. I have the gcd for 1.8 and 2.9 versions of Jill tts voice but I am not able to extract the vpm file. I have tried removing the first 60 bytes using hex editor and saving as vpm file but ttsvoice editor says invalid file.

JCV and lane assist are working. Thanks to wonderful contributers.
