I have tested this method of enabling phone book and other locked out functions while in motion on my nav equipped Accord and have found it to work very well.
I had to make this post in more than one part to allow picture insertions.
The parts required cost about $15.00 at most. The first is a GPS cable extension you can get here: http://www.ebay.com/itm/HRS-GT5-Mal...871886895?pt=GPS_Antennas&hash=item5b01c7ac2f
The second is a DPST switch. I got one at Radio Shack. They have several styles. Amperage is not a factor.
A switch is to be installed in the Vehicle Speed Pulse (VSP) wire (see diagram) from the PCM to the Nav radio and the Operation Restriction setting of the radio set to VSP. A switch must also be installed in the GPS antenna wire to prevent the radio from detecting motion using GPS data. A double pole single throw switch can be used to do both simultaneously.
Remove the radio. There are more than one Youtube videos on it. One is here:
Please note that you do not have to remove the panels around the instrument cluster, only the panels to the left, above and below the radio. Also, the emergency flasher button wire connector must be removed first and the tab to press is on top and out of sight.
The VSP wire is the larger diameter red wire on the F connector. It is pin 7 (the diagram shows pin 10 and is in error) and it is next to a black wire of the same diameter. There is one other red wire on the F connector and it is a smaller diameter wire next to a green wire - that is NOT the VSP wire.
