Thread: Garmin Map Pilot for Mercedes-Benz cars

In fact, I ordered my new cla class with audio CD with prewired system for garmin code 355.
My first intention obviously is buy an unused sd card in order to save some money. But, on the Internet, there are many sd card, but all are Audio 20 CD touch pad version, and as you know the cla class do not have touchpad.
For this reason, I was wondering if maybe the touchpad version can used only with the standard controller, in other words if this version is compatible with audio CD without touchpad.
Although, at the first sight should not be because there are an especific version for cars without touchpad.
