Was digging around and wondering if there was any tricks to doing a parking brake bypass without having a relay. Like if i just ground the parking break wire and touch the lower left quadrant thing. I appreciate it. Thanks. 

If it is an EU model firmware then yes,

You can do a manual switch. Ive done it on one of my radios in the past and it worked out great.

Same as the App Radio 2 bypass stickied above.
