That's it, Steve.

I want to use OSMand, which can be done totally offline so long as the maps are downloaded.

This is not for general planning (for want of a better description), but for those emergency times when you need to change your destination at short notice.

Online route planning on a phone or tablet is not the most pleasant of tasks! but it can be done.

Of course, I could just use my phone (or tablet) in those circumstances, but the times I have wanted to use these "emergency" routes invariably involve heavy rain, crappy paths and sometimes some dodgy areas - times when a discreet gps device is simply handier and safer.

Wahoo told me that the "ping" was not necessary and could be removed. I just wanted to let people who may be swayed towards a Wahoo device for this reason that it is still not resolved.

I'm in Holland and a phone signal is not an issue here, a bit more erratic in some parts of Europe. I'd imagine it's a bigger deal for people on the other side of the pond where there's more open space and less cell phone towers.

The Garmin Touring device has the ability to select a destination on the fly, but my experience with the unit overall was that it was totally unreliable. It crashed regularly, lost routes regularly and totally undermined my confidence in its ability to guide me in an emergency.

I'd imagine that the ability to create and use a route on the fly (albeit using third party apps) without the need for data/wifi would be a big selling point for a GPS device.
