Nowadays navigating is done via a mobile phone or a navigation system. The navigation system has the advantage that you can enter multiple points on one route. The advantage of navigating via the smartphone is that you are always 'up to date' with the maps. It just depends on your preference but the fact is that they both have to be mounted on a secure holder.
At Blue Rider we have made a selection of different phone holders and navigation systems. We only offer the best brands such as TomTom, Garmin and SP Connect.
