I use SD with an iPad 3 and during the navigation I lose the signal (I do not use an external GPS) for a couple of minutes and the find it again with all the related issue because this is not a nice feature.

Somebody has/had the same issue with the signal?

I‘m thinking to buy a new IPad with an internal receiver but I‘m not sure to solve this kind of problem because I think that is related to the receiver and the loss of signal with the altitude and maybe an external one is better.

Thx
