Garmin 705 sync problems

[400bhp]

I've just come back off a weeks hol, got into work and tried to sync my Garmin device with my laptop. Instead of the unit going into sync mode, the unit is powering up.

I've tried reinstalling the drivers but it hasn't worked.

Any ideas? I wondered if work has put some kind of block on the usb ports whilst i have been away....

Try plugging it into the charger to see if it goes into charging mode!

Thanks-i used the charger whilst on hol. It actually synched no probs with my home laptop.

Will try again at home.

I find I have to buy a new cable every so often, I just get a cheap one from Tesco. When one is on the turn it is exactly the same symptoms as you have but if I press it slightly to the left or right it will make enough contact.

Mine had similar trouble a while ago 400bhp, have sent you an email that they sent me, hope it's of some use.

Cheers Potsy - I have tried a soft reset. Will have a go at a hard reset once I have checked it works on my home laptop later tonight.

Just remembered how I resolved mine, re-formatted the thing, lost all my data but at least it worked.
I think you'll have your stuff logged elsewhere Strava/Garmin connect etc so should be OK.

yeah-at the most will lose today's rides hopefully.

Tried everything - hard reset, boot block. Device can see the Garmin EU map on the sd card but not the Garmin folder in explorer.

The port got a bit wet this morning with all the rain - wonder if it's fried?

Is it not sync'ing on any PC ?

 

[potsy]

That's not good, how old is it?
I always worry about the little usb port on mine in the rain, doesn't seem terribly well protected.

Not on the 2 I have access to, no.

23 months old. I think the warranty is a year?

Note: Just been out and bought a new USB cable - still hasn't worked.

I emailed Garmin last night - awaiting a reply. Back in the bag of rice tonight to see if it can remove any moisture.

Airing cupboard or top of radiator, with USB cover off. What a bummer !

Fixed (I'm too impatient to wait for Garmin support to come back to me )

The problem was the corrupt GARMIN directory on the unit apparently.

If anyone has the same problem, then have a look at this thread on the Garmin website, in particular post #32. Importantly it contains a link to a zip file of the garmin base map which you need after formatting the drive.

Note: importantly, to force Garmin to go into sync mode (at the very least so you can see the F: directory on the unit), then you need to hold down Mode and UP on the unit and and then plug into the computer. This is actually quite difficult and often I found it would go into hard reset mode (which is by pressing mode and start/plug into computer). The way I did it was to have the lead already plugged into the laptop but not in the unit. Then hold down mode, plug the cable into the unit, then as quick as you can press and hold UP (whilst still holding mode) until you see the little computer screen.

If anyone needs any help and comes across this thread, send me a message and i'll try and help.

I'd suggest if you own a Garmin device to have a backup copy of the main files on the unit (making sure to copy the directory names and their particular order too) and to back up history files at regular intervals. Luckily I only lost 2 days worth (40 miles) of data.
