I should have said "mine seemed to be able to".
ie - could handle full postcodes.
Not that I have a great need for it.
Mine doesn't. Just updated both the maps and the OS.
After the first 3 digits - e.g. "LS8" it throws me back to a screen offering "LS8 ,1" or 2,3,4,5 (as the last digit). If I choose the first one it then asks for house number and then street name. If I persist by using the "back" button, then I can, after several of those, get to enter my own full postcode. At which point I get "No results found. Try adjusting search parameters". I've tried with and without spaces. And the many other ways I can think of to get at a full postcode address.
Those complaints (though not about this specific device) reporting a similar problem described it the same way. Basically Garmin doesn't want to accept those last 2 digits, but has it's own slightly convoluted way of getting to the precise address. What it does mean is that if somebody tells you - "my postcode is XXX XXX, number 12" this device won't find it.
Maybe there is a way. Though I've yet to find it. And here's the thing. If manufacturers make a consumer orientated device then it should be easy for the average consumer to use it. Though I can sorta kinda get round it, it's friction, and perhaps it tells me a little about the company. There might be a helpline, question is, can I face all that consumer assistance involves?
In fact, I found a youtube video of somebody using the 810, and postcodes.https://www.youtube.com/watch?v=hMX5o0tdmYA
The interface looks very very similar. Doing exactly the same steps, the point he gets to a 1:50 - a full postcode - is what I can't get to. Which presumably means that it's supposed to work the same, but there's a bug in the OS for the Edge Explore.
Just had a long conversation with Garmin. That's the way it works, it's not a bug that's going to be fixed.
I'll send it back. A navigation device that can't use full UK postcodes isn't something I'm interested in.
So, my first experience of Garmin has been a bit meh.
