Preferably YES, all international entrants will receive a Kenya road map to install in their GPS. This detailed base map contains contoured topographical info, major and minor roads plus ‘000’s Points of Interest. It is available for purchase from RVO by non-international entrants,  The RVO track is 100% precise, so long as you stay on track you will be fine, but WHEN you do stray off track you might need the road map to recover.
