General Car mount, will something like this work?

might work but the 3.5 is now at the top of the phone seperate from the mini jack so no need to put that in the charging slot

 

This would be perfect if it works - one plug that would take care of power and audio...

For that price, I might just try it myself!

 

that's why i said it might but htc only pushed the audio through there cause it had no 3.5 jack. when i load hero on my g1 it still works but i can't garantee it will work cause they might be piping the audio through just the 3.5 and left the mini for just charging and connecting. it's a chance your going to have to take it's only 6 bucks to find out.

 

OK, I must be missing something here, I don't understand the purpose of this as a car add on. Both the USB port and the 3.5 are female, same as the phone, so the phone won't actually plug in to this without additional cables. Nothing in MY car accepts a standard USB connector, so I couldn't plug it in to anything there. I currently have an auto adapter in my car, and a cable permanently plugged into my stereo that fits the 3.5 jack in the Eris. I don't see how this device improves on that in anyway.
What am I missing??

 

The hope is that when this is plugged into the bottom of the phone, you will then have both the audio and charging coming out of the bottom of the phone. You can leave this plugged into the cig lighter and the aux in your stereo at all times, the just plug your phone in when you want to listen to it.

 

Has anyone tried that adapter yet?

I found another one that specifically says it works with the Eris:

This one would need a mini-USB-to-headphone adapter though.

If either of these work, I'm in for three: work/home/car...

EDIT:
The same site has this:

That would be sweet! If I rig this up in the car as a dock, it would plug into my car stereo for audio, USB for power, and a wired headset for when I get a call!! That would be perfect!!

 

This is the list of items I have and in order to make my car mount/dock.

HTC Mic from purchased from t-mobil 9.95
Bracketron from BestBuy 39.95
Bytech mini portable speaker from BestBuy 19.95 (optional)
Casset tape adapter 9.95
Mini USB Extension in order (optional)
3.5mm stereo speaker wire extension (Optional) Radio Shack 8.95
Htc mini usb headset adapter from amazon.com Ordered on in yet 5.95
Dual usb port car charger (optional) amazon.com 9.95

Currently it works great, noted I have a wire exposed hanging on my rear view mirror. The usb extension and 3.5mm speaker wire extension is to reroute the wires around the A pilar to go underneath the dash and back up to my mount.

I placed the htc mic in my sun visor and it's clear and legible using my cassette tape player as my audio output.

I got the speakers for my wife's van since I don't lile the fm transmitter especially when driving long distance. You have to keep on scanning different channels. FM modulators ore better, but too much work and may void warranty of vehicle if not installed properly .

I just keep my Bluetooth ear piece handy and and turn on the widget on if needed.




This is the HTC adapter you need. There are two mini usb out, one is for the HTC proprietor mic and headset adapter and the bottom is for the usb charger. The HTC mic adapter will not work by itself, you need to plug in a line out or headphones. It also have and optional 2.5 and 3.5mm jacks if you do not have the mic. In my understanding some of the older HTC phones does not have a 3.5mm jacks, that's why they cam up with this option.

With this device, you can charge your phone and have the speaker phone features.




I will update the images later when I have all the parts in.
