Look at bad elf, I have a plug in job but they make wifi/ blue tooth, they're designed for aircraft so you also get altitude !

Hi Charriot, do you still have your old iPad with gps? If so you could do a clean reinstall of the operating system and then reinstall your navigation app/s. That will speed it up heaps and you'll then have a dedicated nav device. I did this with my old 3g iPad and it works well.

Thanks for suggestions, I like a Bluetooth connection, hope there might be more to choose from.
my old unit is still perfect running Garmin BlueCharts
new unit, didn't find the way how transferBlueCharts, unless
new purchase through Act. Capt.
than I downloaded iBoating Aus. , interesting charts.
plus Garmin chart plotter on boat,
sort of back up, 3 different representations
occasionally anchoring on dry land, most of the time dead accurate

What about this one....
Garmin GLO 2 Bluetooth GPS

I checked BadElf, that's excellent, Bluetooth is bit pricy

Phew the wireless bad elf gear is expensive ! That Garmin kit should be good I'd recon. I wonder if hot spotting your phone to the iPad enables the phones GPS to work with the iPad ?

Yes I've wondered that too, let us know if you find out?

Out of curiosity I gave it a go, hot spotted my elcheapo Optus android phone with location turned on to wifi only iPad 2, opened up navionics on the iPad and presto there I am ! Will look into it a bit more when back on board and check accuracy, timing of updates etc

After 6 years happily using my iPad for navigation / 32gB /,
become too crowded. Than time to upgrade.
New one 128gB, wonderful. Well, silly me, no GPS inbuilt.
To be practical, I prefer wireless .....something.
Any suggestion, please.

When I played with a windows tablet a few years ago I used one of these.

Ties up a mini usb port which on the tablet only had one so recharging while navigating is out. Just as accurate and sensitive as a Sirf4 chip puck.

So it can be done, It seems that the android phones are easier to tether than the apple jobs ive been foolin around trying to tether an iPhone 6 gave up !

i have an ipad with no gps. but i have a garmin watch. i update that navionics every hour and treat it like a paper chart.
