Gonna build a non-ASO-spec nav-tower combo for my 690RR. The usual ASO-spec ERTF GPS Unik + Iritrack is of no interest to me so far. I'd rather go with a simple off-the-shelf Garmin or Valsat P as feeding unit for waypoint info into a CAP-repeater. For the uninitiated - a CAP-repeater simply displays the heading in compass-circle degrees ( i.e. 360 for North etc. ) and gets its info from the GPS-unit. So what works? N00b questions to follow.... A) The cheapest solution would be to get an MLR Valsat P from ERTF, hook it to an ERTF CAP repeater. Question: It's available - but is that solution outdated now? By that I mean if there is no longer software updates etc. for the Valsat unit, do present rally organisers support it with waypoint info anymore etc. B) Another solution could be a simple Garmin recreational GPS feeding a CAP-repeater. Tony Schattat has made such a CAP-repeater compatible with Garmin 60-series. Objective: - Make simple, programmable waypoint info available through CAP-repeater headings for adventure rides - programmed on my netbook. It wont replicate the true challenges of the ASO GPS Unik ( waypoint indicator arrow and info is OFF until you're within 800meters from waypoint ), but present basic navdata for adventure-riding without moving map data.
