I have SS v4.8 on my Droid, runs awesome. But I noticed two Google apps that aren't allowing for updates. One is the Car Dock and one is the Maps Street view. Both fail when I tried updating.
So I started with the Car Home. Went into Chevy's Tools(which rocks btw) and deleted the car home apk file, then did a reboot, went to the market and re-downloaded and successfully installed the latest google car home. That's all fine and dandy, except it doesn't show up at all in my app drawer and when I try and open it from the market it says it's installed, but the 'open' button is greyed out. I've tried a few reboots and nothing. It's no huge deal, I can use an alternate car dock, but I like to know the 'why' LOL.
I haven't messed with the street view thing yet.
