In order for the speed to be bypassed there HAS to be something to interupt. If the speed is dirived from either a CAN bus or GPS itself then it won't be quite as easy.
However, if the speed IS in fact based on GPS it may be possible to defeat the GPS antenna. If the antenna loses power, the Navi unit will lose GPS, thus losing speed, thus allowing you to program while in motion.
Keep in mind, that whenever bypassing speed information there are side effects. Usually placement is lost for the duration of the interuption. Also, any mileage calculations (MPG, oil change, etc) will be off.
The KPtech module is designed to work WITH the OEM 'OK' button. So, before the VSS portion can even be implemented it would have to be possible to tap in to the 'OK' button. I have never personally seen the Navi unit in the Commander so I have no clue if it is possible.
The Navi 'OK' bypass on the KPtech site was designed specifically for Nissan/Infiniti vehicles, but, due to the nature of the module, it may be possible to use it on other vehicles.
Anyone near Dayton, Ohio?
