Problems with Garmin Legend HCx

Hi
As I'm new to this group I thought this might be the best place to get
an answer to some recent problems I am having with my Garmin Legend
HCx.
1. When I updated my software to version 2.40 it seemed to work havoc
with my unit.
2. No longer can I acquire satellites even though I o to the Satellite
status page and press the 'Menu' button, then
Select "New Location", then Select "Automatic" and finally l et the
GPS acquire for about 15 minutes, stationary, with a clear view of the
sky.
3. The date on the unit remains at the 28th September 2007 and the
time is shown as 15.35, the time I did the update yesterday.
4. I though a hard reset might solve the problem but no.
Would anyone have anymore suggestions as I was wanting to use my unit
on the hiking/rambling trip tomorrow?
Thanks,
Gerald
