Anyone come across this

Quoted message said:

Any ideas - anyone else had this problem and managed to sort it out.

Could it be down to 'road buzz' breaking a connection somewhere. The
batteries would be my first guess. Try putting foam or newspaper in the
battery compartment to keep them still.

I wondered about that this morning and have got hold of some foam to try.

Sometimes the MOD carry out GPS jamming trials so that they can fool 'Johnny

I have a Garmin Venture GPS that I use for both walking and cycling. Last
time I used it all appeared fine, but I came to use it on Sunday having
charged 2 sets of batteries just in case and things were not right.

I held it in my hand and let it get a signal, placed it in bike and set
off within a few hundred yards the screen went blank.

I stopped and reset and tried again - the same.

I stopped and changed batteries and tried again and the same.

I was meeting some people so having arrived 15 mins early I had a look at
the thing held it in my hand for 5 mins and all was fine. I put it on the
bike for 10 mins all was fine then I got on bike and within 200 yards the
screen went blank again.

I was not pleased so packed it away as I didn't want to be reminded of
it.

On Monday I went for a walk and switched it on with the same batteries
and hung it from my bag so it was swinging about really. I got to my
destination and it had worked fine no problem and the journey was
accurately mapped and distance was fine.

It is just not liking being attached to the moving bike.

Any ideas - anyone else had this problem and managed to sort it out.

Dodgy wiring, doesn't like vibration.

I have an eTrex Venture and it also shuts off, but only after fairly
serious bumps on the road. I'm pretty sure it's the battery contacts.
You could try stretching the battery springs a bit so they are tighter.

I can see how that would make the unit inaccurate, or make it lose its
position entirely, but how would it make it turn itself off?

Suspend it from some thin bungee elastic so it can wobble around a bit
instead of being jarred by every bump. An old-fashioned handlebar bag
support might make a convenient mounting point.

My old Garmin GPS12 which took 4 AAs, in two stacks of two, suffered from
the same problem. It only happened when I fitted it with NiMh batteries. I
came to the conclusion that the slightly larger diameter of the batteries
was such that the springs were not strong enough to push the batteries in a
stack back together when jarred out of position.

Garmin have had problems in the past with dodgy battery connections on
certain models due to the variation in size from one make of battery to
another.

A phone call to them may provide an answer.Their after sales service is
excellent.I had a faulty unit replaced FOC when well out of warranty.

Not the same thing, but might help anyway.

We race Radio-Controlled model cars and a problem we used to suffer from
was the receiver batteries losing contact in the battery holder. Easily
solved by soldering cells into packs and using better connectors.

The problem was exascerbated when changing types of cell, from Ni-Cd to
Ni-mH for instance, or different capacity cells, as the cell sizes vary
by small amounts.

Known problem on B&W Etrex; two cycling colleagues have had the bad contacts
problem on three B&W Etrex (one destroyed in an accident, and then
replaced). Colour ones seem better.

I had same problem with a digital camera and I believe it was the same
cause. It was OK on a speed bump but off road tracks sed to make it switch
off.

Garmin were good enough to give me a new Quest unit, following the
demise of my own unit after it fell off my bars on an audax... smashed
to bits on a Cheshire lane.

Can't fault after sales like that!

Well known problem on bicycles and motorcycles. The batteries get
jarred out of contact by vibration or a heavy shock. You can pack the
batteries in more firmly with a a little bit of foam or maybe a folded
rubber band under the battery cover. You can strengthen the battery
springs by packing a bit of much thicker stiffer foam or rubber behind
the lever battery contact springs. Or you can soft mount the GPS,
e.g. on a resilient foam pad.

Another possibility is to solder a small capacitor across the battery
contacts if there's room.

The Garmin bike mount attachment for my GPS III+ comes with a little
widget comprising a pair of conical springs in a plastic
figure-of-eight, which you fit between the lower and upper pair of
batteries. This makes the battery fit very tight, and stops the cells
moving around. Since this gadget is part of the manufacturer's
accessory, loss of power due to mild shock/vibration is clearly a
known problem. Quite why they can't do as one poster suggested and
simply stick a fair-sized capacitor across the battery terminals I
don't know. Capacitors which are really hefty in energy terms can now
be found in really tiny packages - and they aren't particularly
expensive.

Mine (the Venture and bike mount) didn't come with such a gizmo. I have
however put some foam in the inside back of the battery compartment and it
was definitely tighter getting the back on. I have also adjusted the battery
terminals.

Both these suggestinos from posters here. I will give it a try at the
weekend - haven't got time before hand.

Just have to try and sort out my odometer now as that has started playing up
too.

At the weekend it "missed" 5 miles from 45 on each of 2 days and I noticed
that when travelling my speed could vary between a reading of say 20mph and
5mph whilst being constant.

New battery in - but will probably try another. Adjusted magnet between the
2 rides.

I had similar with my etrex Legend on my bike a couple of times; I
changed the batteries (from Tesco AA Alkaline to rechargeables, which
I'd just bought for it). I've not had the problem since (I now use it
with the NiMH ones all the time). As others say in the thread, I suspect
it was just the size of the batteries/dodgy contact or similar.

HTH (even if it is a bit late, sorry)

Finally got to try this method at the weekend with a 74 mile largely on the
towpath rn and all was well.

Thanks for the suggestions
