Car Sat-Nav -Marine use?

[JIM_TEAL]

I am thinking about getting a sat-nav for the car. Has any forumite seen or used one which can also use marine charts Eg Navionics C-map so that I can have a chart plotter on the boat?
Is this idea of dual use posssible and what spec do I need to look for?

I seem to recall Garmin do it, a land/sea satnav/plotter.

Here is another Garmin, the GPSMap 620. Both marine and land use. I liked it because it is touchscreen and doesn't waste any space on buttons. I don't know if you can get UK road mapping for it though.

Main reason for me getting a chartplotter would be to be able to display AIS data. Just waiting till the electronics industry gets around to producing a VHF radio that also does AIS receive and transmit, all in one box.

Or a chart plotter with AIS built in, rather than an add-on.

Oh yes please... something with around a 5 inch screen... internal GPS and AIS... touchscreen... weatherproof.... rechargable or 12volt direct.... A nice portableish standalone with a tidy little mount that you could mount on the rail of the binnacle and then just unclip the machine and take it away.... in fact why not have some solar cells on it to help keep the charge up as well...

Maybe have a USB input for chargin from a lappy.. and loading waypoints and routes and chart updates...


MMMM target price.... £299.

 

[Twister_Ken]

Yerbut 7 inch, not five.

Hmmm come to think of it... 5 inch is gonna be a bit small for all that info....

But thats gonna be more like £399 then...

Still.. sign me up.

Looked at the same question and came to the conclusion that 2 units, one marine one car, were cheaper and did their bit better. Funnily enough, thats what the Garmin man at the boat show said despite showing me their two marine + car units. So I took his advice.

the Navicom DSC VHF does receive (not transmit) AIS thru a single aerial. We find it great!

Thanks, that's useful info. And you're right - the single aerial is a another advantage - no need for duplicate aerials or splitters.

I'm aware of 2 other vhfs that do AIS receive as well as the usual dsc radio stuff, all in one box - Icom 505 AIS and Garmin 300i AIS, both rather heavy on the wallet. (They also generate fog signals, which would be another niggling problem solved, never have liked aerosol horns.) I always thought I'd have to connect the vhf/ais box to a chartplotter to see the ais situation.

But photodog takes the idea even further - all marine electronics in one box. So that is an adaptable multipurpose touchscreen display screen, behind which sits gps, charting and tides, dsc vhf radio, ais receive and transmit. Lets add in the engine instruments, depth sounder, log and wind too. Battery monitors, diesel and water tank levels. Anything else?

There'd be a waterproof cockpit version plus a larger backup display for the accommodation. Oops, I forgot the internet access, weather info and dvd/music playback. Remote controls to alter the displayed content eg go from engine+chart+depth to wind+chart+depth (and then to M27/A34/home+traffic as the OP wanted!)

Back to the real world: I don't think the electronics industry would do it, they'd prefer to maintain their revenue by selling lots of separate boxes (look how long its taken them to get vhf and ais into one box.) But I'm fed up with multiple boxes and would prefer more integrated systems.

One word. Well, four actually.

Single point of failure.

Hi Jim, I think yo need to consider how much you want from each type of device. For me, SATNAV is generally something I need a bit at the end of a journey. On the boat I wanted a backup GPS with chart plotter. I ended up with small Garmin Oregon 200 with marine charts that run from Holland to Brittany and the City Navigator software for the UK that gives me turn by turn SATNAV. The whole thing is a pretty small package (fits in my hand). Cost 260 GBP but that did include "boat show special" marine charts. The only real downside is that the device does not talk, so you do need to look at the turn by turn instructions (I don't preferring to stop and look at the route, once I get close to the destination). I am not sure but I think a slightly better model might speak to you.
This setup suits me but it is clear I have compromised on some functionality over a perfect setup (but the compromise on the money spent helps me get over this).
