It is possible to change sound on 510!
It cost some time but it is possible.

On your navman there is a directory called /program files/navman/sound
in this directory there is a .dat file.( for example sp3_fem.dat)
Take a edit program for sounds( for example "goldwave") en import this file as a PCM , 8 bit , Rate 11025hz.
Now you can hear all the voices.
It is 1 file so there are pointers in this file for the right voice at the right place to say this voice.
If you change 1 voice, then change it in the length of which is the voice now. Save as .Raw or .snd. Change the filename back to .dat and put it back on your navman.

I changed the voice "Test" and mixed some other voice with it.
Copied it back to my navman and i heard my new sound.
Off course it cost some time and the length of each voice must be the same but it is possible to change some voices if you want!
