I've got the Mono car charger and it charges in AC mode.
Strangely, I also have a wall charger from mono that I use at work and it only charges in USB mode...

I have bypassed this. What I did was purchase a power strip type splitter that had 2 sockets, and two USB ports. I then purchased another USB to Micro cable. When I plugged my phone in using the car changer it was slow. When I used the USB port it was a rapid charge. Now I have my iPod running out of one USB, and my phone off another USB. I also have two sockets for friends chargers for road trips. I have not had a problem with this in any way, and never have a problem when running NAV.
I just thought I'd pop in and let you guys know that I just got through testing a few devices to see how much actual current they are pulling. One of the devices was the Incredible.
Here are the chargers I tested:
powerPLUG - Low-Profile USB Car Charger
powerPLUG - Low-profile USB Car Charger for iPad
High Powered USB Car Charger | Bracketron
The first is rated at 1.0A while the latter two are rated at 2.1A.
I tested the data terminals on all three and none have a near zero resistance between the pins so they are not providing a simple dedicated charger signal. This is bad news for the Incredible. I also tested a Droid X and a Bionic and both of those will still go into AC charging mode when plugged into either of these units. But the Incredible will not. As far as I can tell from reading the USB specifications, there is another type of signaling that can be used tell the device it is plugged into a dedicated charger but it appears the Incredible is not using it. So to get the maximum charging current, the Incredible must be plugged into a charger that provides continuity between the 2 data pins.
The two Scosche chargers I tested do not appear easy to disassemble. They are probably glued together. The Bracketron charger was relatively easy to take apart, pulling two screws off the USB end (one is under the sticker with the specs) and unscrewing the metal cap on the 12V plug end. Once apart, simply soldering the data pins together provides the dedicated charger signal to the phone and puts it into AC charging mode.
Lastly, I tested the actual current being passed through the cable. To do this, I picked up a cheap microusb cable and cut it in half, exposed the wires and reconnected the terminals using some test leads. I used a multimeter between the two ends of the +5V wires and measured the current. The Incredible only drew 0.4A from the Scosche chargers, but with the modified Bracketron charger, it pulled 0.85A. For comparison, the DX and the Bionic only pulled 0.75A from each charger. The bad news in all of this is unless all three chargers are not capable of actually reaching their ratings, each phone is not able to draw up to or closer to the charger's max current rating. I did test a Griffin Ipad charger and the OE Incredible charger and it appeared similar. Oddly, the phone only drew 0.75A from the OE charger. The only other variables I didn't test is for each device at different states of charge and if the cable had any limitations (it was a cheap cable afterall). Regardless, I thought this info might be of some use to you guys.
