@lattesurf - thanks for the reply
There is no option for sleep, the menu options that seem to do with power or display settings are (current setting in brackets)

- Lum 1 2 (3) 4 5
- BLight Mode (Normal), Power Save

System
- Language
- About = ver 00.00.0032, Date 2006-09-12
- Upgrades
- Default Settings (already tried this)

Power Off Time
- Power Off (OFF), 10 min, 15 min, 30 min, 60 min, 120 min

Further replies would be helpful. Currently I am drafting an email to DataKits requesting a refund which is a shame because it plays music fine no problems. Just the navigation power-offs which are a pain.
