Before I do anything, I want to thank my friend [and fellow golfer] tendriver for his invaluable assistance in helping to finalize this post. For those who don't know, I'm an ex-mod for the iGO section.
Because of information and downloads here, I put together a program that some of you might find very interesting. A friend of mine was starting to receive messages that his maps were outdated. Knowing what I do, he asked for my help. BTW, his device is a TT ONE XL. Not only did I make his maps current but I also included TTS for the first time for his device. I put everything on a SDHC card. The voice I used from VocalizerTTS is Samantha [US English] but you can ask here how to change that. FYI, it is SE Navcore 8.412.1236. It also has auto-activate for the maps.
You can download this and copy it to your SD card. It is complete except for the maps. You would make a separate download of that content for your specific needs. I believe it would work for most devices having a SD slot.
