Your experience is what has kept me from updating the NAV DVD to a recent version. You must have an older lockpick. I have heard that this lockpick will not work beyond 2005. Coastal had come out with an updated one (lockpick 1B v.2) to work with the newer DVDs, however they are of stock and (supposedly) will be replaced by yet another update.

I am thinking of making a hybrid disc so I can keep using the "backdoor" with new version DVD. Perhaps someone here has found a workaround to use the newer DVDs with old lockpick?

Cheers.

Well that sucks. Of all of the times I needed my Navi, I'd say maybe 4 times in 2yrs. it couldn't find a a street name and or street number and I ended up used my iPhone so I guess it's not that big of a deal. Looks like I'm going back to the old disc.

So I put back in my original disc (Ver. 4.2) and now my lockpick won't work...it does the same thing w/ ver. 13. I don't have to push the "I Agree" button but everything else is grayed out while in motion IE: Navi, RSES, Bluetooth. I swear I hate this POS Navi system!!!

I feel your pain. I upgraded to 13.1 and it still cant find housing development that was built 2 years ago.

I have a garmin zumo for my motorcycle with a portable car suction cup mount. The mapping sofwear is from 2009 and at least it can find most things or get ,me close. Very intuitive to use
I thought since my 2004 gx470 still had the original map software that the 2103 would really wake it up. I find it runs slower but it does have more recent POI .

I didn't noticed any difference either. I removed the 4.2 disc and then removed the ground battery wire hoping that fixes it.

I removed the disc a few months back to look at it and when I put it back it, the screen brought up, please wait while it's being loaded. I removed it and put it back in earlier and as soon as I close the navi dvd door the maps load immediately like it's in the memory somewhere, there no more "loading" so to speak. It's almost like ver. 13 upgraded something within the system so it can't be hacked w/ the coastal lockpick.


EDIT: Removing the ground did the trick. I got the "Please insert correct map disc", then when I loaded the disc I got "System loading. Don't turn off the power".

In my 2005 sc430 when you upgrade the map software I did lose the the ability to override the navigation. I bought a beatsonic module and installed a console mounted switch so I can at will override the naqvigation and then put it back to normal. Also did a switch to hack the phone so I can use all B/T functions while I am moving as long as I have the switch depressed.

The new 13.1 map software for my GX470 did not remove the override function so I am good with that don't need a manual switch . My truck is under 3 year warranty so I don't want to make to many mods that could cause a problem .

Have you asked locpick for advice ?

The lockpick works again while in motion. I just needed to remove the ground on the battery.

Regarding the lockpick working w/ v. 13, it won't. Another member said after v. 5, it can't be hacked w/ the version of the lockpick I have and since I didn't noticed a difference it maps between 4.2 and 13 there's no need to spend money on an "updated" lockpick.

The problem is the firmware stored in the loading.kwi file. This firmware is updated occasionally, however I have not completed my database of changes, I can tell you 10.1, 12.1 and 13.1 are all identical firmwares.

Within the firmware I hope to one day be able to patch out the checks for the system speed sensor which it uses to determine the car is in motion. However the authentication of the firmware varies from section to section and I haven't identified the checksum used for any but the first 4 sections.

When you change your dvd to a newer one the firmware is checked and if newer it loads it into ram memory in the car. When you try to insert the lower version disk it fails to find it's newer and doesn't load the old one. By resetting the stereo you get it to reload the factory base firmware instead and thus can get it to load again. Note that the upgrades they made in the firmware such as bluetooth are lost when you downgrade to the older copy. The hybrid disks will work for this reason with newer maps but old firmware. This may be worth it for some to get nav entry while moving.

I'll take your word on it. Whatever you just said is way past my knowledge of how our navigation system works.

i have a 2007 GX470 and dont beeive the Nav has aver been updated, It doesnt even pull up my address and my home was built in 2002. I see that update CD's 10 thru current updates on here are all the same. So would any of you agree i should just pick up versionn 10 on ebay or wherever and load myself?

Also, we lost our 3 buttn keyless remote key. Best suggestion for repalcement and programming?

Up dates from one year to the next adds POI that are new also new mapping is added . They run basically one year behind 2013 update closed out in 2012 and the next update in 2014 will be closed In 2013 . By and large unless your disk version is very old year to year updates are small. if your current version is 2007 then you really would benefit with an update.

The lost three button remote can be replaced on ebay but you will need to be sure you have a working master remote key fob in order to program a new key replacement. I cant speak for the 2007 gx I think you will need the dealer for programing They have a scan tool that they use, In my sc430 I was able to program an extra key by following key vendors instructions. You might look on ebay and ask a vendor about programing

Um ok.

I read on here that all I need to do is slide the eject button to the right and the DVD will come out.
I have done this and nothing happens.
Does the vehicle need to be on? I have tried it on and off and nothing, the disk doesn't come out.

Please let me know how to get the GPS DVD out.

Thanks
