    So I got the ProClip mount for my Evo. I'm curious how the phone knows it's in a holder? :thinking:

    With a magnet in the dock, that kicks it over to car/dock mode.

    Thanks! I thought magnets would hurt reception or other phone functions somehow, interesting...

    from reading around in the accessory sub forum..there are pins in the usb...pins on the dock , the phone recognizes an extra ground in the dock tells the phone that it has been docked.

    there are some folks trying to figure out which pins do what but if i recall correctly the dock has one power wire...and two grounds... the extra ground is what is telling the phone it has been docked.


    some aftermarket usb cables also have the extra ground...and the phone gets confused and thinks it is in a dock.


    never once have i heard this is caused by magnets

    The ProClip holder for EVO I got doesn't have any pins on it:

    EDIT: And the phone's dock mode will activate without even a charger plugged in.

    The Droid 1 car dock does not have pins and it goes into car mode without a cable. The Droid 2 and Droid X docks have a connector, but the cable does not have to be used. Even without the cable it will go to car mode.

    interesting (and i guess i really don't consider it a dock if it isn't plugged in .e. "docking")

    my mistake....i consider these "mounts" haha...

    so...who has an answer on how these mounts know? when I mount mine in my vent mounts and windsheild mounts it doesn't auto do anything special.

    is it really magnets? that just seems odd...UNLESS it is in fact a low strength magnet..that does something to the accelerometer ...but without effecting the compass ...hrmmmmmmm

    i love the proclip look btw...let me know what your overall impressions are

    Yes, it is talked about on Engadget, and various forums including Motorola forums.

    I've had the ProClip "mount" for almost a couple weeks now and like it a lot. Not exactly inexpensive, but a quality product with a "swede-like" covering that won't scratch the phone. It also holds the phone firmly in place, allows you to swivel the orientation, and has room for the phone with larger batteries and back covers.

    I actually took off the stock attachment holder - the part that attaches to a vent mount or such, and installed a RAM mount base. Had to drill a couple extra holes in the mount, but no biggie. This allows me to use and quickly switch between having the mount in either the car, or on my motorcycle. :)

    HI, I purchased the same dock from ProClip, except mine slides into a power usb at the base. However it doesn't go into "docked" mode, even though I have that setup in settings. Are you saying that just sliding your phone into that felt covered holder with no power, puts your evo into "dock" mode?

    It does with mine. I do have Auto-Launch checked in the Dock settings though.

    Interesting that ProClip has more Evo mounts now.
