I recently read a post by a knowledgeable member saying that one or more of the bounty hunter models had received a circuitry upgrade in 2004 resulting in faster recovery/response time. Does this upgrade include the pioneer 505/LandStar? I can't find even a single reference to the recovery/response time for the 505/LandStar on the net. I know that the discovery 3300/Legacy 3500 has poor recovery/response, but I'm hoping that the 505/LandStar is faster. Someone help please!
