Poiloader.exe and sox.exe

I recently was in Gary Haymon's nuvi tricks, tips web site trying to find out why my boa doesn't show the boa symbol or boa ahead anouncement doesn't work. I know from the past when someone sugested I make sure all three files are the same and I checked again and found that the mp3 and bmp had a single underline at one point and the cvx had a double underline so I did fix them at this time and will check it out later. However the web site was talking about having only one poiloader file loaded on the harddrive ( I do and it is in c:\Garmin ) and I should have the latest sox.exe file also. I could not find that file anywhere on the computer. How do I find this sox.exe to download it on my computer.

Gary, if you read this you have emailed me a couple of times in the past, I wasn't sure how to contact you through your web site.

Thanks for anyones help at this time.

Brian
