I used to be a Navi muffle. In my hometown Berlin I am, however, encountered in the past on several occasions on my orientation limits. So a Navi ago. Selection criterion: Well, the price (in South Africa need no navigation aid!). My first contact with the unit was great. Intuitive operation, Routenaenderung moment during the journey will be updated very quickly. On foot (through forest trails) Top! The manufacturer provides to a variety of tools, for example, to change the output voice or to create their own voices. Have to take several trips with the device previously had only positive experiences. Conclusion: myself am amazed at the quality of the art. As I said has been a Navi muffle. Can thoroughly recommend this device
