Get yourself a copy of ISTA+

It's far more advanced than INPA and it's more suited to the newer BMW's - E70, E60, etc. Really great for diagnostics.

Bridging the pins on the K+DCAN cable is only for older BMW's - E53, E39, E46, etc. If your cable is working with your E53, then your pins may already be soldered or bridged somehow. This means it won't work on your E60/70.

You've ordered a cable from a reputable site so it should be fine, but for anyone else ordering a K+DCAN cable for their E70 from Ebay or AliExpress, make sure it has the green PCB (printed circuit board). The white PCB's will often work with an E53, but not an E70.
