  1. I can override the motion lockout for the nav system using the techniques posted in this forum. However, my bluetooth handsfree telephone system is still locked out. Does a way exist to override the handsfree lockout in the same manner as the NAV override? Thanks.
  2. Here is what I believe is the situation. 2005 RX 330 has Gen 4, version 4.2 firmware and maps -- override works Gen 4, version 5.1 firmware and maps -- override works Gen 4, version 6.1 firmware and maps -- override fails Gen 4, version 7.1 firmware and maps -- override fails Gen 4, version 5.1 DVD has a file named loading.kwi. This file changed in version 6.1 which is why the override fails. The hybrid DVD takes the Gen 4, version 6.1 files and replaces its loading.kwi with the loading.kwi from the version 5.1 DVD. One has to burn this on DVD+R DL media at no more than 4X (burner must be able to DVD+R). Gen 4, version 6.1 + loading.kwi(version 5.1) = hybrid 6.1 DVD -- override works Theoretically, this will work with the version 7.1 firmware, but I have not had time to research that issue completely. My initial thinking is that some other changes have occurred that may prevent this hack from working. Also, once one loads one version the only way to go back a version is to remove fuse TV-1 for the Nav unit which powers it off and it will then do a complete reload when power is restored. The same could be accomplished by removing the battery cable and then replacing it. The problem becomes one of finding a version 5.1 and 6.1 DVD. I did find this site for downloading loading.kwi but have not had time to study it. So much for now. It is late. HTHs YMMV Mike
  3. Yes you will be able to override the system, it's just map update This post seems to suggest that installing ver 7.1 will disable the override. The poster says that a hybrid disk is needed. I have a 2005 RX 330 Gen 4, 5.1 and do not want to lose that feature. Would someone that has installed the ver 7.1 DVD please confirm that it does not remove the ability to override the Navigation Motion Lock. Thanks, Mike
  4. yes it will you need to make what they call a hybrid dics if you want this function, i have made one for my gen 2/3 nav I assume the same problem exists for 2005 RX330 Gen 4, 5.1 to 7.1 in terms of losing the override function. Would you please post the instructions on how to make a hybrid disk or paste a url for where one can find that information. Thanks Mike
  5. If I understand it correctly, installing a new version map DVD also upgrades the software? Does the installation of updates disable the ability to override the navigation lockout feature on a 2005 RX 330? If yes, does a workaround exist? I really do not want to lose that capability. Thanks Mike
