How is it possible to identify my Gateway 100 firmware version?

Please select GW UI (Gateway User interface) mode, turn the head unit off (car stereo), wait few seconds than turn it on. The version number will be visible (after the checkmark) on the right upper part of the iPod’s screen (at the same time when the Starting screen is visible) in the following format:

G1_nn_x.yy

where nn shows the hardware version of the Gateway 100 while x.yy the firmware version. In the upper left corner of the same iPod screen the car brand is displayed for which the Gateway is configured.

Please note: This procedure doesn't work with Touch (1st & 2nd Gen), iPhone, iPhone 3G. If you have one of these devices only Accessory Attached will appear in GW UI mode.
