LOOX COM Ports / settings

HI

Can anyone help me.

I've been running my FS Loox N560 fine with TOM TOM and Wi-Fi.

However, I've recently lost GPS - I get a message that says 'No GPS Device'. I can't connect to Wi-Fi at home either (it did a week ago) - says I need to change the settings!

I did mess around with things last week trying to set up a Bluetooth connection but it could have been my young kids playing with it?

I think the problem maybe something to do with COM ports but I don't really understand them and so am struggling.

Any advice much appreciated.

Cheers
