GPS/ Navigation

Hi all.
I've an old, working Navman car Satnav that takes maps via an SD card. Does anyone know if it possible to get inland waterways maps for the UK?

Imray have their own solution for inshore navigation via their C-series charts. Supplied at various scales, these river and a passage charts feature complete, up-to-date depths, with a coverage that spans beyond the UK to help one navigate their way through the inland waters of Europe.

Aside from inland passage nautical charts, one of the most essential boatman's tools for navigating those inner watery tunnels are pilot guides. Showing broad and narrow canals, navigable rivers, non-navigable waterways, locks, tunnels and much more, these guides come from the likes of Imray, the Royal Yachting Association (RYA) and many of our other favourite publishers. Offering a more detailed set of instructions than charts, you can find everything from full pilotage details to the location of popular pubs in these fold-out guides, making them an indispensable navigation tool.

I think you will struggle to find an old car sat nav that will work with charts.

Thanks for the quick reply - I'll look them up.

I had a chat with an electronics guru years ago about similar ... and he reckoned that it would usually need access to the programming code of the Sat Nav - to modify it to accept other formats.
According to him - many are based on a proprietary vector style for each brand .. and that is why you cannot upload as example IGO to TOMTOM etc. The fundamental info may be from same sources etc - but by time each brand has had its hands on the info - its been modified to only work with their units.
The same actually is with Marine Charts, other than those smaller sets some have. Where as example units can run CMap but not Navionics etc

I did at one time run an old Car unit on the river ... but the unit had the User option of choosing 'Jump to Road' or not. This is where the unit if has it selected - will 'jump' the cars position to the nearest road - as long as reasonably close. You can see it happening on car units when you are in slip-roads / entry / exits of motorways etc ... your car appears to be running along one lane and then jumps to the correct one etc. With the older units - you could turn this off ... which if you were not an off-roader could be interesting.
But with my old unit - I could truck along the blue river - no info of course other than speed and position. I think my latest TOMTOM and Navigator units in my cars will still allow me to follow off-road and rivers - but because the Jump to Road is not user switch-off'able .. may be interesting when near a bridge / road etc.

Thanks for that, I'll check the unit settings next time I'm onboard.
