## Customer Reviews

### ⭐ Useless!
*by W***G on 8 September 2018*

I could not get it to work. What little info on the screen was in Spanish and the box was also printed in Spanish, It would not respond to any button commands. A great disappointment. I sent it back on 6.08.18 and still not had my refund.Enough said!

### ⭐ TwoNav lack of Instruction / Support.
*by A***N on 19 April 2022*

TwoNav GPS instruction (or lack of) might as well be written in Klingon. No help from support. Its going back tomorrow!

### ⭐⭐ Ridiculously expensive for something which is too small to be of use - and does NOT come with complete map coverage as advertise
*by C***L on 13 January 2015*

Only a brief review, as the weather hasn't been good enough to really get out in the hills. I'll update later with more detail - but first point to note – this is very small for a GPS. Now, if all you want is co-ordinates, that’s fine. Unfortunately, if you want proper mapping, then it’s a problem. While the maps are detailed, the screen is simply too small for easy navigation, and the interface is sluggish and non-intuitive.Anyone who can afford this can afford a smartphone, which will do the same job much more effectively. It’s far cheaper to pay for an armoured casing and an external power pack than one of these.
