Having now taken the DMD tablet on two or three trips, I’ve made some progress with it but I find there are still some serious problems with using it that amount to deal breakers for me.

First the positives: I’ve worked out how to turn up the volume and assign a button to that so I have been able to hear the turn by turn instructions from Google Maps and DMD – when riding at slow speed at least.

I’ve worked out how to tether my iPhone to the DMD so now have a live connection that allows Google maps and Myrouteapp to work properly.

With stick on fingertips on my gloves the touchscreen works pretty well most of the time.

These are all major problems solved. But there are still some unsolved issues that make me consider deinstalling this outfit and putting it up for sale:

1 The screen is not very bright – nothing like the Garmin Zumo XT and I can’t understand why people say that it is. See the picture. DMD is set to 100% brightness. It is pretty much unusable when the light shines directly on it, in even dull sunlight.

2. The link to the iPhone keeps dropping out and is long-winded to reestablish involving two separate set up screens – certainly too involved to do safely while riding. And when there is a poor mobile signal, there is no GPS mapping – at least on the Google maps app.

3. The DMD app map seems to have centred itself in a large blue ocean somewhere and does not seem to auto centre on where I am. Again, this would take time to sort out – involving stopping.

4. When using it, the map does not seem to keep where you are updated.

The pros still are: I can just take one device on journeys that I can use as a Kindle, for internet browsing and blog updates
