LOL, yeah, I tried calling and got nowhere.
I see many people talking about doing a bypass on the Z1 and Z2 - what is this exactly - from what I can gather it is over riding the system to able to watch DVD's whilst the car is in motion ?
Yup, you got it. It allows you to do everything you CAN'T do when the parking brake is disengaged, including search addresses using the on screen keyboard, watch video, dial phone numbers by number, modify POI view settings, etc.
Also, I've done a little more research into the HD3 Vs. Z2 question. On top of the obvious differences with different maps and different POI's specific to the area, the manuals indicate the AVIC-HD3 is MISSING the following Z2 features:
- [*:49czp32m]Telephone search[*:49czp32m]All NavTraffic features[*:49czp32m]Emergency Info feature[*:49czp32m]City View[*:49czp32m]Language selection[*:49czp32m]All of the features introduced in the Z1 to Z2 upgrade, including:
- [*:49czp32m]ability to show or hide address book icons on Nav screen[*:49czp32m]a few new alternate voice commands[*:49czp32m]lower-case letters on keyboard[*:49czp32m]New routing option "avoid roads with time restrictions" (like draw-bridges)[*:49czp32m]2D and 3D twin view selectable from Map Mode screen[*:49czp32m]3D landmarks in 3D view (there's only 3)[*:49czp32m]NavTraffic event icons have smaller icons when zoomed out[*:49czp32m]a few new bluetooth address book options[*:49czp32m]Changeable Splash screen
Also, it appears the default Vinicinity Search POI Shortcuts are different.
Other than that, they're the same unit, as far as I can tell.
