Have spent a lot of time on this one. If you have a Generation 4(hardware) Nav system (gen of nav is different thing than the dvd version being used) the hybrid between 5.1 and 7.1 doesnt seem to work. have had success with 5.1 and 6.1 but the 5 and 7 combo doesnt work on a gen 4 machine like my 06 GS300. Several others with gen 5 navs have reported success burning a 5 and 7 hybrid.

I tried the override thing on the GS350 tonight where you press menu -> volume -> tap top left, bottom left, top left, bottom left but the other menu never came up with the override button option. What did I do wrong?
BTW, it's an '08...

This could be an interesting experiment.
Anyone who already has installed a Ver 5.1/6.1 hybrid disk. If you get a Ver 7.1 disk you should just go ahead and install the latest 7.1 disk.
My guess is because the Ver 5.1 loading file is already loaded as your NAV system firmware you might immediately have the 7.1 maps and also have the 5.1 override.

^^^ I don't think that works because once you put in the 6.1 or 7.1 the system automatically updates giving you the firmware from that DVD. I'm like 90% done on my hybrid disk, it works but its kinda slow when navigating through the menu. I will try to re burn it using a different brand DVD.

Some references in here. look for the post from timeToy. several of us spent a lot of time on this last year. nobody with a gen4 system was able to get a 5/7 hybrid to work. 5 and 6 yes. several people with gen5 systems did get the 5/7 to work they say.

I've burned 7 hybrid 5.1/7.1 disc and no one works. 
I'm wondering if my 08 GS nav ecu is not taking any old firmware. Anyone here is So. CA with a gen 5 5.1 disc wanna meet up and let me try the disc. Wanna make sure that my nav ecu will take older firmware or not, before i waste more disc and time.
