Latest Voice Pack issued by Garmin for SP c3xx devices was in 2007 (V2.60) however it doesn't contain Bulgarian and has only limited major European Voices (not even RU):

Be aware that these early SP devices are not Mass Storage Mode capable. Therefore, simply adding files like additional VPM voice files isn't possible.
If you already know that, i guess you are wanting to make some software modifications which will add a BG voice capability. That may be technically possible as i'm aware of experts being able to add Italian to US English-only voice software for the early Honda Goldwing navigator (based on SP 26xx). However, in that case the compatible IT voice code was available to extract it and then add it to the device's voice region (17, hex 11). So, you'd not only need to find a suitable BG voice, but you'd also need the expertise to be able to add it into an RGN file to flash to rgn17. That requires advanced coding skills beyond that of most people.
