Is it true that the performance of the stock nav system is slower than a Garmin or Magellan unit? I've read so many reviews about this sort of thing and most people say you are better off buying separately one of the Garmin or Magellan units and doing it that way. Someone told me most stock Nav's today aren't as efficient and accurate and you have to buy high end cars to get good Nav's. That's all hear say I know, so don't blame me for bad info, I'm just going by what I've read, this could be wrong.
