Clarification for external GPS+compass unit

Hi,

I own the APM 2.0, the one with internal Mediatek GPS.

I bought this:

I successfully plugged the external gps by soldering the pins 2 and 3.

Now I want to use also the external compass, but the instructions are not very clear. Is it enough to cut the SDA trace on the GPS board?

I'm a bit afraid because once I cut it, there is no going back...

Thanks!

Michele
