What is the spec of your Galaxy - Zetec, Titanium etc ?
If they did forget to give it to you, there should be NO problem at all as it won't be car specific, so they should hold them / have it sat there
EDIT: Just had a very quick look on the front page of Ford's Galaxy page and if you have Titanium upwards, it comes with full european sat nav...
Additional to Zetec:
- Ford DAB Navigation System with full European mapping data
- Privacy Glass – dark glass to rear windows
- LED Daytime running lights
- Automatic front headlights
- Rain sensing front windscreen wipers
- Keyless Entry
- Lane Keeping Aid
- Traffic Sign Recognition
- Cruise Control with Active Speed Limiter
- Chrome trim to lower side windows
- Chrome Roof Rails
- Automatic dimming rear view mirror
