Please beware that this product does not work with the Android 1.5 "cupcake" software release as of 15 May 2009. It works with the previous release of the system. I will update this review when I get it to work.

Update: Toggleheadset breaks with Android 1.6. I've switched to using CyanogenMod, which fixes the bug!

Even with the update, there is a lot of alternator noise in my headset when plugged into the cig adapter on my Toyota. Clear as a bell without power enabled.

The product works as a splitter, or if you want to talk while the phone is charging. But if you are looking to listen to music/navigation while changing, please note that the included 3.5mm or 2.5 mm ports will NOT work! It is not that they are defective but they are only for wired handsfree for phone communication. For music you still require the HTC 11pin to 3.5mm converter that came with your phone. You may use that adapter with this splitter to listen to music while charging but that becomes a messy setup - 2 adapters, 3 cables, 3 connections. I eventually bought a bluetooth car kit for music, navigation, and phone; and charge the phone directly when needed. So don't use this splitter anymore. You might end up doing the same unless you don't mind 3 cables. Another alternative is FM transmitters, but those don't compare to BT neither for quality nor convenience.

This item actually has the HTC logo and is specifically designed for HTC phones.

This device allowed me to connect a 3.5mm stereo plug to my sound system to play music from the phone. Also, I use the 2.5mm stereo plug to connect to my car stereo.

Whats more, you can even plug a car/home charger into the device at the same time as the stereo plugs. This is very convenient in the car with a car charger. I made an adapter like this before with the Cingular 8125 but the problem was you would hear a "whining" sound in the stereo when the car charger was plugged in at the same time. With this device, you do not have that issue.

Its a very nice multifunction device, and at the price its selling for, you cant beat it.

I bought this so that I could play music from my phone into the car speakers with the line in 3.5mm port AND charge at the same time. Previously i used my stereo bluetooth pilot that takes a 3.5mm or just the adapter that has 1 converter to 3.5mm. These worked. I plugged my car line cable into the 3.5mm on THIS multi-adapter and nothing! it was charging, but not playing music. My work around was to plug the single adapter i previously used into the original android headphone port on THIS multi-adapter... this worked! if i didn't have this single adapter i would have returned it. i can listen to music and charge my phone at the same time without running my stereo bluetooth pilot battery down.

This does work with the G1. But you need the Sound Route Switcher app. Then it works perfectly.
