I just had the Eclipse AVN5435 installed in my 06 HIHY I am having a problem with the speed pulse wire not allowing voice guidance or route correction due to issues with not having the correct speed wire connected. I recieve the correct reading on the diagnostic screen but it will flash a speed pulse message some times. Has anyone successfully installed this or any other aftermarket nav system in the highlander hybrid? If so where did you connect to the speed sensor wire? My installer says there are four wires in the Hybrid that send this signal to the ECM but none of them seem to work correctly. Does anyone have a wiring schematic to trace out a correct wire. Any suggestions?
