Very strange Speed warnings!

Was travelling on M25 / M11 today. I was doing 70mph. However my Nuvi 2699 randomly (short spells of time) giving me speeds of 42/23/19 etc. This resulted in Garmin beeps warning as I was doing 70 on the motorway.! These speeds randomly came up at random times whilst on the motorway.

Off the motorway (in 30 mph area) it showed speeds of 12 mph when I was doing 30mph and the obvious warning beeps!

Not sure what has triggered this and how to fix it.

Possibly messed up your feet/mph and metres/kph setting when updating your database with POILoader. There is a pinned thread on the subject just above here. Likely picking up the roads that run along and across the motorway. Re-install the database ensuring the correct selection is made.

It won't be the Garmin maps.

It's most likely an incorrect setting on PoiLoader.

Try running PoiLoader again, and be sure to select feet/mph (not meters/kph) on the screen where it gives you a choice of these, on a drop-down menu.

When I read the first post I got the impression the Garmin itself is picking up an incorrect speed causing the speed cameras to be triggering.

Is the internal GPS chip failing or getting blocked by something.

I'm with Kremmen. That was my initial thoughts too.

I have a DS61 LMTD and am more than happy with it apart from its occasional strange routing (But they all do that)

I don't know as I don't have a 65. Is the 65 purported to have a sim slot? If so, what the hell for.
If it comes with speed cameras, they will be Cyclops ones. You can disable them and install PGPSW if you prefer.

The likely reason for the map update fail is that Garmin servers are reported to be out.

They've been hacked so have shutdown servers.
