You need to pay and download from the Garmin website first and then insert the memory card into the slot for the system to be updated. I have a 2013 too.

Could overfilling the system cause the clutch not to engage? If so I'll just release the pressure. Should I release the pressure with the car running or off, or it doesn't matter because the compressor clutch doesn't engage? It also happened to my previous Mazda 6 when I overfilled by mistake using...

I believe you overfilled the freon. I had the same problem using the gauge that came with the can of freon. I let the freon out a little bit at a time and check the psi at the low-pressure port in the garage rather than in the sun outdoor and fixed the problem.

Price?

Interested, how much?

I for one in Toronto!
