CatchMeIfYouCan631 Posted August 18, 2008 Report Share Posted August 18, 2008 so isnt that like shutting the computer down manually? Quote Link to post Share on other sites
Stephanie Posted August 18, 2008 Report Share Posted August 18, 2008 I do not think a hardware-only hack will work. Just supplying power to the RAM with everything else remaining the same, will not help and might even hurt. A sleep-mode or hibernation-mode would have to be feasable in the software first. The OS, the applications, would need to 'know' that they have a sleep / hibernate state. Otherwise, on car power up, the thing's not going to refer to the ram, it's going to go through whatever it does now, i.e. a boot up. It's dissapointing that Pioneer didn't see fit to include the parts of WinCE that control the shutdown behavior... any WinCE experts know, could we add the shutdown.exe and whatever libraries are required?

HackZ Posted August 19, 2008 Report Share Posted August 19, 2008 Come on people Ur all getting close to figuring this out, someones got to get it. Quote Link to post Share on other sites
bobtheg Posted August 19, 2008 Report Share Posted August 19, 2008 I emailed Pioneer two weeks ago about a standby, or hibernate mode.... No response Sux cuz this is the only thing (besides the nav boxes) stopping me from buying the f700. I really don't want to buy the JVC 7000. Quote Link to post Share on other sites
Bman69 Posted August 19, 2008 Report Share Posted August 19, 2008 i'm not really thinking about how we can keep the unit on or sleeping but how can we speed up the boot cycle theres gotta be some things we can make quicker, i need to research wince more Quote Link to post Share on other sites
bobtheg Posted August 19, 2008 Report Share Posted August 19, 2008 Well if you want to speed it up, maybe some of this will help:: Registry:: Boot Sequence [HKEY_LOCAL_MACHINE\init]"Depend100"=hex:1e,00 "Launch100"="Gpsmc.exe" "Depend105"=hex:14,00,1e,00 "Launch105"="\\windows\\shell.exe" "Depend95"=hex:14,00,1e,00 "Launch95"="dw.exe" "Depend60"=hex:14,00 "Launch60"="services.exe" "Depend30"=hex:14,00 "Launch30"="gwes.exe" "Launch20"="device.exe" Registry::Overclock the processor [HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Performance]"CoreClockMin"=dword:0000000c "CoreClockMax"=dword:000001f4 Can someone who has installed the firmware update, host a copy of the new registry. I'd like to compare the two. Quote Link to post Share on other sites
Bman69 Posted August 19, 2008 Report Share Posted August 19, 2008 is regedit in the headunit? i dont think i tried that yet Quote Link to post Share on other sites
CatchMeIfYouCan631 Posted August 30, 2008 Report Share Posted August 30, 2008 Anybody look into these options in the control panel? Quote Link to post Share on other sites
NickyD32 Posted August 30, 2008 Report Share Posted August 30, 2008 i have, but i didn't know what to make of it... i've heard its possible to overclock the processor... and i mentioned in a thread a while ago about possibly changing the boot sequence... like starting GPS last or something... im sure that would really help Quote Link to post Share on other sites
stevfuri Posted August 22, 2009 Report Share Posted August 22, 2009 in case anyone hasnt pointed it out, hibernation needs the amount of non-volatile memory equal to what is currently in-use in the system. Hibernate (or sleep) works by pausing the OS to save anything loaded in resident memory to the harddrive. When it unhibernates, all this is read, put back into memory and then unpaused. This means that the AVICs would need to come out with another flash or some other non-volatile storage device to keep the hibernation image. I doubt they have enough flash storage available to do something like this. It's important to reiterate the difference between Hibernate and sleep since the words are confused in several places on the forums. Sleep is a low power consumption state where the hardware is still running. Hibernate is a dump of RAM to Long-term storage and then all hardware is shut off. The difference is basically speed of reinitialize. Hibernate would do almost nothing for start up time while sleep could make all the difference. A Possible Soultion for Stops Could a smaller 12v Battery (Say a marine battery) be wired in parallel with a toggle switch to the power input of the AVIC? Then before turning off the car simply toggle the switch "on" ensuring the AVIC doesn't realize the car has turned off and continues to draw power from the backup battery. When the car is running the backup battery will be charged by the alternator just like the main battery and when the unit needs to be turned off for long periods just flip the switch. It's also possible to turn off the screen to increase the battery time of the backup battery through the built in "System Settings"1 menu. 1) PG 138 English f90bt manual Quote Link to post Share on other sites
