Hema HN6 Hardwired

Hi Allan,
I have an original Hema HN1 navigator and want to replace it with a Samsung tablet, You said you are running EOTopo on yours, is that with Oziexplorer?
Do you know if it will also run Natmap maps and Hema maps.
Which tablet do you recommend, and any traps to watch for, I would like about 8" screen.
regards,
JohnnyC

Hi Johnny,
Yes, I am running EOTopo with OziExplorer on my Samsung Galaxy Note 10.1 tablet.
I can also run my collection of Hema digital maps on this tablet but I am not knowledgable regarding others or limitations. There are some on this Forum who certainly could answer those and other questions.

This link to EOTopo may be useful to you.

The HUD doesnt charge anyway it only has ACC power for when car is running Says so on the box

Seems I have been lucky, everything worked after I soldered the plugs back on. I checked the polarity with the cut off plug when it was plugged in to make sure I wired it correctly.
I notice the Polaris hard wire kit has a small box in the positive so maybe it does step down. The reverse camera I am installing has a similar small box in the harness, had assumed it was just a fuse but it seems its probably more.
A lot of wasted time lesson is buy the manufacturers hard wire kit if they have one. Just trying to eliminate the cables on the dash.
I appreciate the input given.

Cheers Peter

Would be sensible to look at the specs in a brochure as it usually tells you the voltage it works on. Lesson is to find out first before rushing in and making a fatal mistake.

Learned that 40 years ago when I metered the wrong thing in an expensive stereo and it cost me more than it was worth to fix what I shorted in it.
Usually the ciggy plug has the in and out voltage stamped on it. If its a stepdown it will and if its just 12 v it usually doesnt.

Do it with all of them as the cameras dont like too much voltage.

Mine was a 12v one but ran hot so built a little stepdown from Jaycar and ran it on 8V and it ran cool.

I went one step further Rob. I made up a 5V, 6Amp regulator which I hard-wired to several 5V devices, dispensing with cigar lighter sockets altogether. I have the resources to do such but your method is otherwise good.

Yep that way you can take it with you when needed in another vehicle Cut the end off and unless you have a spare cord you are stuffed.

I have used the stepdown power supply kit from DS to make a rear view camera run cooler with slightly lower voltage . I have used the ciggy sockets wired into a spare fuse to run two dashcams. 5 minutes and its all gone when you change the vehicle.
Also made up a longer cable to take dash camera on holiday overseas to use in the rental cars.

Tom, Once you get a Troopy you never "change the vehicle". LOL

But I am not promoting my unique setup methods, simply imparting them.

Had a 100ser. Like a bit of comfort LOL

Now run a pair of VW's.

Gave up the nomadic life.

I think in my box of cords and patch cables and adapters I have every combination known to man except the one I need when Im looking for it ROFL
