GSID Upgrade?

[samastonlongley]

I have a 4.3 Vantage Manual which like all Vantages has the GSID. However because mine is an early Manual car it only tells me when I'm in reverse and when I'm hitting the red line. Is it possible, or does anyone know of an upgrade, whereby it can be updated to show you what gear your in when driving? Like they are set up in the sport shift cars?

Thanks
Sam
