[storminmike]

I've been reading the Dale Cregan Trial commentary with interest and at todays session I read this

Start at the bottom an read up.....who'd have thougt that sat navs held this amount of information:eek:

excerpt

The Garmin sat nav device then heads south and is back at Gainsborough Avenue in Oldham at 11.59pm.

The following day the device remains switched off, as it does on August 12,13 and 14, says Mr Lang.

However, he refers to a mobile phone which the Crown say is attributed to Mr Ali, telling the court, using cell-site analysis, it is plotted heading from near his home address to Bradford and Leeds city centre on August 11, the day after the gun-and-grenade attack in which Mr Short was killed.

The sat nav device is turned on again in August 15 when it is plotted again heading towards Bradford and then to Leeds around noon, the court is told.

During this journey into Yorkshire the device is plotted at the White Rose pub and at a McDonald's drive-through restaurant in Leeds and at the Silver Birch Carvery south of Bradford, the jurors are told.

At 7.15pm the sat nav system leaves the motorway and turns up the A640 where the device is switched off, the court is told.It is switched on again at 8.06pm when it is plotted just south of Bradford, says Mr Lang.

Then the device appears to turn round and heads back towards Manchester, returning to Gainsborough Avenue in Oldham, according to the witness.

At 8.40pm the sat nav system is on the move again and heads north and arrives at the Waggon and Horses pub in the village of Hawkshaw, north of Bury and Bolton, the court is told.

It remains there for two hours and 35 minutes, says Mr Lang.

12.12
The sat nav device was plotted at Gainsborough Avenue in the early evening of August 10, the jury was told.

Later it moved to Press To Impress on Lord Lane in Failsworth.The Crown say this was where Mr Ali picked up the men accused of murdering David Short before taking them to Bradford.

The device arrived at the premises at 6.32pm, remained there for four minutes and then moved off heading north west, the jurors heard.

It was at nearby Mona Road for a few minutes before heading off towards the M62 and then towards Yorkshire, the court heard.

12.01
Mr Lang started his evidence by explaining his area of expertise was examining sat nav systems or anything with a microchip in it.

He told the jury he found 207 'recoverable journey entries' which plotted 59, 956 points on a map during his examination of the sat nav system associated with Mr Ali.

I'm not sure how this works. Does it do this benign or does it do this once a journey is plotted

Bit of a spy in the cab whatever the method

I'm guessing it only does this on plotted routes and as it makes alternatives up on the fly if you change your mind or go another way it must re-calculate. I was shocked that it seemed to have "written" the route with timming ways points. Maybe they could be deleted, maybe they couldn't.

Wouldn't surprise me what else is written when blu tooth devices are linked together
