Thanks all... great info.

I think for now, I will do a small Nuvi mounted on pro clip by the vents and hide the power wire with a hidden feed and not a lighter socket feed.

It will be the cheapest option while I live with the stock system and save my pennies. If ultimately I get a deal to retrofit, the Nuvi should be very sellable. (although I could put it in my truck ... a 1985 F-150 ,how cool would that be )

Again, great info at short notice and I promise I will start posting my mods to add to the data base,
