yeah, I think I'm gonna do the same. I'm in a bit of dilemma with the whole Carpruride thing, as without a BMW Nav Cradle, I need to go for a model with BM05 interface and with that taken in the account - an appropriate mount bracket, Carpruride W702S Pro (that was my original plan) + BM05 + interface adapter etc. etc. - nothing looks that elegant or cost-effective.
Now I'm thinking to go for a used a used Nav cradle and Carpruride W702BS, which clips directly into the Cradle. So, off to eBay now
