Yes, the Griffin card dock is terrible. I'd say don't even bother.
There are plenty of great car docks that can hold a Maxx and let you plug in a cable when you want to power it. There are a few wireless charging car docks but I'm not sure they work well through a big case.
I like iOttie docks because their suction mount will stick on anything and will never release until you pull it off. They make a Qi charging dock as well. Pricey, but maybe your best bet if manually pluggin in is undesirable: Amazon.com iOttie Easy Flex Wireless Qi Standard Car Mount Charger for Google Nexus 5 4 LG G3 G2 Nokia Lumia 928 920 Motorola Droid MAXX MINI HTC Droid DNA 8X and Other Qi- Enabled Smartphones Cell Phones Accessories
I've never used that one myself, but it should work...
