Anyone usied a tablet with GPS in place of a chartplotter or conventional GPS ?

Not in place of, but for back up. (several times) I dont think itll be long though before they have a dash mount for the ipad or other tablets

you can't see the ipad good in sunlight.

I cant remeber the boat but the owner had them build an ipad into the dash. It looked real sick. I think it was to control the music.

Yes, my ipad as back up using the inav app

windship has the ipad mounted on the dash. I just downloaded navionics for my iphone, I am going to it a go tomorrow crossing lake ontario and see how it does

The Navionics App on the iPad and iPhone work great. Only problem is seeing the screen in the sunlight or while bouncing around. You will need a plug adaptor as the battery drains quickly with the GPS active.

Let us know how it worked please.

heres my thing on IPAD, whats the purpose. I mean you have your lap top which isnt much bigger, and then your phone which can do everything. To me I cant justify buying it because its a useless inbetween device IMHO.

I have the Navionics app on my Motorola droid phone. Great app and beyond worth the money for at least a backup.

But like everyone else is saying, you can't see it for crap in the sunlight. It might be better if I had bimini top, but I don't, so it is just tough to read.

I have had it mounted with the car mount on the dash and it is semi helpful, but the real GPS is way easier to read because of that coating on the screen (purplish tint stuff). I wish you could get that coating in film form so I could put it on my phone.
