Car Dock Recommendation for the S4

[ddsdavid]

Another vote for the iBolt. I bought mine for my DNA. After 5 DNA replacements I bought the S4 and the charge cord for the DNA wouldn't work on the Samsung. One email to iBolt and 3 days later I had the correct cord without needing to buy a new dock.

Great product and great customer service, what else can you ask for?

Is this auto go into car mode a function of the ibolt cord connector or is it detecting a data connection? My truck has cigarette lighter charger but no USB data port.

car mode is not configured in the kernel build and is not available on the s4 (even though the resistor value and code is still there)

i believe that desk dock mode is now used as the trigger to start car dock applications such as car home ultra

this is likely triggered by the detection of a 365k resistor between the ID and ground pin on the micro usb cable, so yes, it is a function of the car dock or a custom cable that you build yourself.

With all my questions answered, I think ibolt is the one. Thanks to all!
