Hema HN 7 on Android Tablet

I bought a HN 7 last year & very happy with it. I just have a question. I am thinking of buying an Android tablet and just want to know if I can use it to run software to interface with the HN 7 instead of having to take both the laptop PC & the Tablet with me on travels

Hello

Depends what you mean by "interface". You certainly will not be able to connect the HN7 to the Tablet and transfer data in the same way you can with the PC (e.g. HN7 to PC via Hema Explorer).

If you choose to place OziExplorer (Android version) on your tablet, the same maps and data (waypoints/tracks) can be used on both units. However, while on the road you will most probably have to transfer data between the two devices by way of interchanging sd cards. I do not think it is possible to "interface" between a HN7 and an Android tablet in any other way.

Thanks for that info. From what you are saying it looks as if I can run an Android version of OziExplorer on the tablet and with that plot tracks & waypoints. But rather than interface directly with the HN7 I will need to copy the waypoint & track files from the Tablet to a USB memory stick and then from the memory stick to the HN7.
I have used a netbook in the past but a tablet seems to be a lot less cumbersome & easier to use and has a bigger screen. And it can be charged directly from the vehicle 12v system rather than having to use an inverter which I have to for the 18v netbook

Hi

You wont be able to use a USB memory stick - they dont work on Android tablets or HN7. As mentioned before I think your only option (in the absence of a PC of any type) is to utilise sd card/slot to transfer data to and from each device. HN7 has micro SD card so make sure you have an adapter if the Tablet you get has traditional larger SD card slot. Suggest you use the internal memory of the tablet a the primary storage point of data you wish to transfer from either deice, so just a case of putting HN7 sd card into tablet to transfer data. Obviously you need a tablet with an SD card slot - I am not sure if they all have them.

Also keep in mind that the android version of Ozi has less functions than PC version..does all the basic stuff you need to show where you are, record waypoints, tracks etc which is maybe all you need but if you leave the netbook at home check you aren't hobbling yourself in some way.

Cheers

your overcomplicating things.
all you need do is is plug your tablet and hema nav into your PC and just drag and drop the maps into a map folder and waypoints etc into a folder youve named data on your tablet then direct ozi to look for maps in the map folder and data in the data folder
Apple users especially can get confused as the simplicity just doesnt make sense

Dave

You need to read the thread from the beginning. You have missed the point about there not being a PC on hand (while travelling).

I guess I will just have to get used to the limitations of the Android tablet. Maybe I should think about a Windows tablet. Haven't really done any comparisons on the merits of the two. I have just been assuming that after my pleasant experiences with an Android phone that an Android tablet is the way to go. Android just seems a whole lot easier to use than Windows in a mobile environment

All depends on your personnel requirements. I was just pointing out limitations to make sure you were aware. I almost always toss in the netbook when travelling in a car (for reasons other than navigating - android tablets and ipads are close on useless for a wide range of more "serious" applications).

Small screen gps is really all you actually need if you want to navigate, record track and waypoints...but if you are in a car the bigger screen of a tablet/ipad/laptop is handy I suppose.

If you have an Android phone then you can test everything you want without buying a tablet because the tablet is just a phone without the telephone part and it has a bigger screen. Are you expecting the Android tablet to do things your Android phone won't?

No mention of any phone so far...so doubt there is any unreallistic expectations.

And keep in mind that registered version of oziexplorer Android is linked to serial number of device...so dont purchse until device of choice chosen. Demo version works Ok so no problem testing on range of devices.

He said 2 posts back that he had a pleasant experience with his android phone and was hoping for the same with an android tablet?

No worries - my mistake, though it would appear that there are still no unrealistic expectations from the tablet (i.e. same "pleasant" experience anticipated). Nonetheless good suggestion - trying the demo version of OziExplorer on an existing Android device is certainly a good way to see if it will do what you want prior to going one step further and purchasing a tablet. The demo version does everything the registered version does though gps communications bombs out every 15 minutes and has to be restarted (and the Word TRIAL plastered over map screen).

depending on the tablet memory sticks certainly DO work on tablets (although probablly not all)
all id do is exactly what i said - if he is on the road id just pull into the town library or comunity telecentre .... exactly as i said
to much over complication

You think that removing and inserting SD cards is complicated? Would surely have to be faster (and less complicated) than driving into a town (if one happened to be nearby), tracking down a library/telecentre (if the town had one and it was open), finding a PC and hoping all the necessary drivers required to communicate with your HN7 and android tablet are installed and then transferring files.

I have never seen/heard of an Android tablet/phone having a normal size usb port that would accept a USB stick...let alone correct comms/drivers to allow data transfer. If they exist they are in the minority....or I am blind Freddy (possible:)

...but wait .. there are USB stick adapters for Android devices

Android USB Stick adapter

Doesn't help much for case being discussed though as it wouldn't work in the HN7...

Suppose the next question is do they have cables that run from the nearest library / telecentre to the middle of the Simpson Desert (so things don't get "over complicated" :)

you would normally get organised before hand
im just letting you know that many tablets have the capability to run USB sticks without interfacing with a computer
also my coment about librarys and telecentres is also valid
he just mentions about being on the road - many to most even out of the way places have public access to computers so transferring like ive mentioned would not normally be an issue
my biggest mistrust about exchanging SD cards is ive learnt not to do this if possible as on a few occasions ive ended up with devices saying the card needs formatting - where ever possible i use non card removal options for this reason --- paranoid? maybe but as I said i have been bitten before let alone the risk of losing the tiny things

anyhow theres no question transferring data like he requires has no one correct answer and the proverbial "more than one way to skin a dead cat" comes to mind

Sorry for getting sidetrack with Dave..yes , if you were considering the android tablet as a full replacement for your netbook (which you already have) maybe not a good idea. Netbook will do everything the Android Tablet will do and more (though a tablet is good for some things). HN7 will obviously do the job in the nav department...and you wont have to visit any librarys :)

Have fun

Nelson,

HEMA have an App for the Android tablets for $29.99. At that price you can't go wrong. Maps can be down loaded so you can run off-line. I run on my Sony Xpiria.
