iPhone 4 Car Kit

Hi everybody!

I need an iPhone 4 Car Kit. I hope you have some good ideas.

Currently i have a Belkin Car Kit. But it is only for iPhone 3G & 3GS.

I wrote to Navigon about a new Car Kit for an iPhone 4. But unfortunately they don't developed a new one.

Which Car Kit can you recommend to me? Perhaps you know an universal Car Kit. That would pretty nice.

Thx!

No one use a Car Kit? No ideas?

Is this iGrip compatible with an iPhone 4 & Case for example the SwitchEasy Nude Case and can you turn this Car Kit in landscape modus?
