HD2 LEO back side pins[Q]

[Sir Andrew CZ]

At first I would like to apologize if this topic already is somewhere there. I didn't know how to call thouse pins so I didn't know what to serach for.

When I look at the back side of Leo I can see three unused pins. I remember HTC Himalaya, where thouse pins were for extension pack with VGA OUT, CF slot and next battery.

Review of the cover

Does anyone know what are thouse pins for? CF slot is death but VGA OUT is usefull. Older QC generation was able to VGA OUT so why Snapdragon wouldn't?

Cannot believe that/

Problem solved

So one has to remove the battery cover in order to put the HD2 in the car holder?

Sorry, but this I do not believe it, I have never seen such car holders that demanded removing crucial/standard parts in order for the device to be able to function.... (Apart from a small rubber (dust)cover....)

Please document your findings with a link.

Personally I believe this is more for service/mantenance/diagnosing a broken device by tech support.

believe it, bub. As retarded as it is, HTC has made it that way with the HD2. The car holder will activate the Navpanel (via the 3 pins in the back) while charging the phone at the same time.

So in order to use the car adapter one should everytime remove the battery cover?
That's really retarded : where to leave it while driving? in your pocket is not to comfortable

They should mention that in the specs before one pays around $90 for that piece of cr*p
Bought mine at Dealextreme for under $10, works perfectly, only need car charger....

CAR HOLDER. Not car adapter. HTC made a car holder for the HD2. It has a suction cup stuck to the front windshield. The car holder is there to activate the Navpanel for using GPS program.

The car holder was to ship with a new battery cover which connected to those pins.
Search google for "Official HD2 car holder" then you can see pictures of it, it was actually
a very nice design, not retarded in any way.

Replacement back cover is not so bad
But I still don't know WHY buy expensive original holder with this "speciality" when I can buy 3 dollar holder on eBay with normal attachment...

 

[extrapurifier]

These pins were for the original HTC car holder which never came to market. Therefore it was necessary to replace the rear cover permanently and stick with it at the car holder.

The now available HTC car holder is using a hughe plastic thing and the HD2 gets connected via Mini USB.

Neverteless, it would be very interest how these pins are usable for personal mods and so on. does anyone knows which functions they provide or how they can be used?

sorry to dig up a massively old subject, but I figured I would jump on the end of this instead of a whole new thread, now that this thread established what the subject matter is.

I want to put an induction coil in my phone (using a plastic back-plate obviously) and I'm wondering if I could feed power into these pins, obviously they were meant for charging so they should accept charge from other things, does anyone know the polarity of the metal tabs so I don't fry my hd2 with trial and error?

 

[FunFrog]

davidcampbell, did you try it? Cause i wanna use that two pins for charging and don`t know polarity too...

 

[FunFrog]

Seems like i have an answer. We need a block with 3 pins behind a battery cover, where left is minus and right is plus.

Is this confirmed? Have you tried connecting power to the leads? Ive been contemplating turning the phone into a din-mounted stereo when I switch carriers and would like something better than microusb for power.
When powering these leads, can you remove the battery and still run the device? Unlike the microusb...

I,m also intrested in connecting cheap china wireles charging coil to those pins. Also I found out that they are used by Powermat Wireles Charging System for HTC HD2. Here you can see a picture showing this plug. So it seems that pin 1 and 3 is used for charging. But not shure about polarity.

With battery door removed & looking into the back with the 3 pins in the bottom left the left most pin is +5v & right most pin is ground ...

I beg your pardon!
Prompt. There were official comments of the existence of this car holder (uses charge pins) from the HTC company?


Sorry for my language (google translate).
