|
|
Hi there
I am looking for a GPS that will work in the car with street maps and on the boat with charts. The boat one is a backup to the main GPS.
Is there a model out there that will do both. Based in UK so need UK maps.
Regards
Graham |

Yep - but it's not going to be the cheapest solution out there....
A GARMIN Colorado 300 will run as a nuvi look-alike with the NT2008 maps and you can also load BlueChart Atlantic onto it, for mapping as you would get on a dedicated ship-based unit.
The draw backs are the small size of the screen, poor sound and lack of touch screen.
I don't believe the nuvi systems can use the BlueChart maps correctly as they don't understand the icons used. Note: this is certainly true of the 3xx/6xx nuvis - don't know about the others but they don't appear on the BlueChart support list. Shame about this as they could make passable ship based units - except for their lack of outdoor ruggedness. _________________ Phil |

The problem is the requirements for the boat and car are very different. No one had really successfully made a combined unit, as there are just too many compromises to be made.
Alternates are a PDA with say Tomtom for street maps and memory map for charts (in an otterbox when on the boat) or a top end Garmin handheld.
Both have drawbacks, Personally I would look seriously at a Garmin handheld for the boat (You can take it with you if you go for a walk as well), and a dedicated, in car system. One thing to ask is do you really need a backup in the boat?. How reliable is the main system? You should be able to navigate your boat without a GPS, if you can't a training course would be a better way to spend you money. (Please don't be offended, I am not being demeaning or condecending, I have no idea of your marine background or skills.) |

I believe Memory Map's Road Angel, despite it's name, can be loaded with Maritime Charts. This will give you Road sat-nav, OS Maps on land, and use on a boat.
Check with Memory Map at www.memory-map.co.uk

Very good advice and equally applicable to all places you would use a GPS - air/sea/land. It's an aid to navigation NOT a substitute. _________________ Phil |

I use my Garmin nuvi 250 as a back up GPS device at sea, firstly it gives me a fix anywhere which is nice, but you also need a paper chart as well.
Secondly it will take me home, sure it will take you straight through a pile of rocks, but used intelligently it's dead handy in a small boat in fog in familiar waters, as it helps to avoid disorientation.
I used it on the train today, why do Intercity 125 trains only do 100 mph?
I have to tell it I'm on foot and off road of course, and I have changed the car icon for the blue triangle pointer (wish it were red). |

Very true, A few years ago I was on the bridge of a P&O Ferry in dry dock looking at its GPS on a big screen and it shown its position about 5 miles inland, I was also on the bridge of an irish ferry coming into Rosslare and it was just the same, I wouldnt risk navigating by them, when i asked the helmsman if he navigated by it, his short answer was no fear.! _________________ Moto G5s Plus, Sygic 17.4.8 |

When I used to sail my boat from Portsmouth to Cherbourg there were three accepted methods of navigation:
1. Use dead reckoning, ie pass St Kate's point on the IoW and then steer 210.
2. Follow the trail of discarded beer cans/bottles.
3. Use Decca.
When Decca died I invested in a Garmin GPS 12, it was an improvement over Decca, it not only gave you Lat and Long, it also showed your track! |

I hate to say this (as a TomTom man) but is the Garmin nüvi 550 worth a look?
It's water proof and is intended to be all purpose: for hiking, bicycling, driving and sailing. |

The Garmin 478 is also suitable for both boat and land navigation. No tts unfortunately, _________________ Garmin 1695 / 255 / 760 w/MSN - Droid w/Google nav + Navigon - Navigon 8100T - Dakota10 - GPSMap76C - GeoMate Jr. |
