I have had emails from number of people saying that there are heaps of mobile chart plotters out there – but I beg to differ!
There are heaps of mobile chart plotters for the Land but not the Sea
For example even Garmin only cover the Land ….Garmin Mobile XT transforms your GPS-enabled smartphone into a full-featured street navigator. Routing software and detailed mapping are preloaded on a microSD card – just plug it into your phone and you’re ready to navigate – on foot or in your car. With no subscription fee or additional equipment required, Mobile XT works anywhere, even outside your phone’s network coverage area.
Minimum requirements for Windows Mobile®, Palm® and Symbian® devices: 16MB program memory, 128MB storage card minimum (256MB or more recommended), 2GB storage card for full coverage
You get :
- City Navigator® NT street maps …one of:-
- Garmin Mobile™ XT North America
- Garmin Mobile XT,Europe
- Garmin Mobile XT,UK & Ireland
- Garmin Mobile XT navigation software
- miniSD and SD adapters
…so when will the Sea version come out – well …never me-thinks – why should they when they have so many solid and reliable handheld plotters already. It is the new entrants into the market that may be motivated to creep in via the backdoor of the smartphone devices. Not the incumbents like Raymarine or Garmin.
