If your unit reboots continously, or

reboots every few minutes, or

you can't access the navi settings menu,

here is an easy solution:

• Boot into test mode
   
  Navigate to the 'My Flash Disk/USER/UserData/iGo/save' folder
   
  Delete all files in the 'save' folder (there will prob be 4 files and 1 folder)
   
  Navigate to the 'My Flash Disk/USER/UserData/SETUP' folder
   
  Delete all files in the 'SETUP' folder (there will prob be 5 files)
   
  Exit test mode and reboot normally
   
  Problem solved!

(you will need to re-enter your settings)

Please post here and let me know if this solves your problem,

- I'm 99.99999% sure this will do the trick.

happy holidays!

what do those files do??? how are we sure that by deleating them we are not doing something else (something bad) to the unit???

The files that need to be deleted are your user settings files - they are written on the fly when you first start the unit up from what I understand.

When the unit keeps rebooting, it's usually because one of your files is corrupt. When you delete the files, they are re-created (good as new) the next time you boot the unit normally.

I've used this technique *many* times and it's worked every time!

The main reason I've needed to use it: trying to install igo schemes that are not compatible with my unit or the files in the schemes call for files i don't have. I'm sure there are a million ways to corrupt one of the settings files, but since they re-create after being deleted, (and they re-create correctly) I don't think this would hurt anything. It does seems to fix things though!

hope this helps,

ps - please excuse my lack of proper terminology, i know this procedure works, but i'm sure my description leaves people who know what they're doing shuddering. i'm sorry! (and i'm eager to learn....)

I would like to add I am pretty sure this was the cause of my rebooting problems. However in my userdata/setup folder the files that were in there were all garbage looking files. I could not delete or rename them. At first it would not let me even rename the setup directory iteself. but after rebooting into testmode for the 3rd time, i was finally able to rename it, still couldn't delete it, but at least i renamed it. Then i reflashed and everything worked great.

did not work at all for me [f90bt]

Deleted all the named files. Unit still rebootinig every 2-3 minutes. I can't even get through one song.

Does it reboot even if you have the system in park ?

Yup. Completly stationary. I noticed that as it tries to load the Nav I never make it past the press warning OK screen as it is still "booting". Music plays and the phone connects, but the second the "system startup" screen is about to go away it reboots.

Next step is to follow this set (http://www.avic411.com/forum/viewtopic.php?t=20119&highlight=testmode) of instructions and attempt to reflash the unit.

Did it always do this (out of the box) or did you make modes? If so, which ones?

Is it rebooting when the phone connects?

Mine rebooted each time the phone connected for a while.

I had to remove the phone from the list. Then re-install it.

You could try with bluetooth off first see if it works.

Just an idea.

i tried the steps listed and all i got was a reset unit. it still resets after 2 mintues and it doesnt matter if i go into the navigation or not. and just like before if i unplug the GPS antenna everything is fine but no navigation. has anyone had my problem and tried the steps in the other thread about re-updating?

anyone have instructions and the files need for test mode start up??? if so please send me a link....

thanks,

Still having reboot issues.

Bump.

Has anyone figured out anything new?

I tried removing the files, but as the system resets every 8 seconds, it seems like 1 in 100 times it will actually read from the SD card. I'm thinking that I'll have to back up the original, reflash the thing, then delete those files and do the Universal iGo license mod (which i still can't find anything on, BTW).

How do you enter test mode? (F700BT)

please help me how do i boot into test mode? I can get into the blue screen with the wince menu but ,i have no test mode where i can delete folders . this f900bt is about to skid down the road @65mph! thanks any help is much appreciated

My F900BT had the same problem before.

I used the testmode method to upgrade to 3.0 from 2.0 via SD with FAT32 format. System did get upgrade but it would continuously reboot every now and then.

After several attempt of re-installing, tried to install with another SD formatted with FAT.

Copied over the same files and magically everything works without the constant reboot!

I don't know the different between FAT32 & FAT but but using the later certainly did the trick for me

Hope this helps.
