I'm an ISIS guy. It's $$$$ but it's completely worth the investment.
Actually I'm combining ISIS with MiMod HP which includes 10" touch screen LCD for all switching functions, AM/FM/CD/DVD/GPS, air suspension operation, TPS, bluetooth/handsfree calling, cruise control, back-up camera, HVAC, twin 7" LCD panels for gauges, all screens custom designed, etc. Even more $$$$ but will be freaking amazing.
