I get the written turn by turn, but...
I cannot get the voice command to give turn by turn directions and the map does not display the upcoming turns. If I press list, I will get a written list of turns. Tony thinks the harness is not compatible since the 1999 ML did not have the MCS and had a different type of NAV unit. My MCS does not say off road, but does pinpoint my location properly most of the time. Also when getting a route, the voice says proceed to the highlighted route, so the voice does work. I am zeroing in on the harness issue. Any thoughts?? Also I have a picture of the 99 wires of you think you can make heads or tails out of the wiring.<br> <br> Thanks for trying, we are all stumped!!
