Sat Nav Features

[tinkerbells]

Does anyone out there know of a Sat Nav that has the following features:-

- "Where Am I?" function - ie, you are lost or maybe broken down and want to tell someone where you are - name of road and town. A question mark (or similar) to press to get the appropriate response.

- Facility to enter an address and then assign it a name, eg "Aunt Pauline".

- Diversion - so that, should for eg, the M25 be closed, you can tell the Sat Nav and it will take you on a different route instead of keep trying to direct you back to the M25.

- "Store this location" with a description (ie, when you come across a pretty place on holiday for example but you don't have time to stop). So you could store the location as "village near Pete's Farm".

- Quickest/shortest route (I'm sure most Sat Navs must have this now but mine is ancient!).

- Facility to upgrade maps from the internet (ditto above).

If anyone knows of a Sat Nav that has all of these features, please let me know!
Thank you.

All of them have the first one ... If it's on, it will always show you where you are.
Most have the rest, better ones like Garmin or TomTom top models have last two, and 3rd.
