has anyone had the problem of when they insert the z2 bypass disc, it says the file is already updated on the unit? Its manufacturing date is july 07. I have not done the update from pioneer yet. I did have a unit from june 07, but the navi took a shit on me and had to return it to one of my distributors. it had the same problem. it said the updates were already on it. Any help would be appreciated. i have done the 2 wire bypass, and after driving maybe 10 feet the feaures cut out.

The cutoff was right around that date. It probably already had the update from the factory. Check your bypass wiring again, its probably the problem
