Apologies if this query is covering old ground but, for once, google has failed to help me find my the answer to my question. What I would like to do is find an app or apps for Blackberry that do the following:

* pre-plot a map/route and then upload to Blackberry (I normally use endomondo for this as it has a real time map view that plots the route being taken against a pre-plotted one)
* have an audio navigation tool give turn by turn instructions to help follow the pre-plotted route (this is the bit I am struggling with as most audio navigator seem to only work when choosing their own route and so not seem to be abel to give directions for a pre-plotted route)

There must surely be a way........................
