Charriot said.. GPS on iPad works well, can see it using TomTom.
iPad does not have standart Nav. available.....just HD.
Sorry you are right. Friend had same problem with iPad.
I put HD version on my tablet and then standard version and found no difference in resolution. I then asked for refund via the interface on the $70 version.
I guess your choice is to buy $70 version or buy an Android tablet cheap and dedicate it to Navionics.
My Lenovo A8 50 is good quality, quad core with GPS chip. It cost $234 at J B hi fi with extended 3 year warranty. Big W and Target have cheaper brands for around $100 but probably not worth mucking around with.
Question!! How do you get a screen shot and then post to forum??
