Anyone come across this

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.

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
Foreigner' if he tries any of his dastardly tricks using GPS navigation..

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.
