Looking for any help or advice please. I have a garmin Nuvi 52LM and have been trying to add premium voices using Jetmouse.

Have done everything it tells me to do including changing the file to a UNL and not a TXT but still nothing. The VPM and the UNL files are showing in the actual device when I look at it on my computer, however, they are not transferring to the voice selection in the device.

Does anyone have any suggestions as to what I might be doing wrong? As I said, I have followed it step by step. Is Jetmouse an old programme? Does anyone know of another programme which may work?

Any help or advice would be greatly appreciated as my old garmin has just died on me and I really miss Homer Simpsons voice!

Thanks in advance
