The law changed July 1. You may now carry LOADED in a SECURED (does not say "locked" in the statute) compartment without a CHP.
Otherwise, the best place to carry your sidearm is on your side. Open carry is not affected by being seated in a vehicle any more than it is by being seated in a booth at a restaurant with your strong side to the wall.
There are a handful of available options for console-mounted holsters, too. Probably the worst two places to "open" carry a sidearm are your dashboard and your passenger seat. In a crash, your sidearm could become a very dangerous projectile. Some people advise against this practice.
I am one of them. Wear your gun.
