New to this forum posting lark

so appologies in advance if I do not post correctly.
Just installed on a Navman (mio 168)... runs slower than my packaged gps but maps are newer (yes my installed maps were that old!)
Only probs I had were (all have been resolved by reading forum posts):
1/Write protection was set to 'read only' on SD card fording me to re-enter my option settings each time I loaded the software.
2/When installing using DVD setup I did was having probs installing map as I had not realise the need to put all map files in map folder prior to install (still learning lol).
Seems to run fine... not road tested yet.. I am particularly interested in clear voice directions as I run PDA as satnav on a my motorbike with PDA out of view so will rely solely on voice prompts.
Much better than my currently installed smartst
I am not a fan of TOMTOM at the mo (largely due to me not being able to get any cr*cked versions to run on my PDA... but that's a different story (and forum!))
All in all an excellent bit of kit

Although I have 1 question... how do you get the voice command option to work? When pressed it says 'No voice command has been stored'.
Thanks in advance
