Hi,

This is my first post.

I have just bought an early E60 530d ( to replace a 1991 W124 200 Merc) and have access to a loaded 2007 550 which lost a fight with a lamp post. The 530 does not have nav, the 550 seems to have everything.

My question is does the ent/nav stuff swap over easily and is there anything else I should take from the 550.

My thanks to those who posted on the swirl flaps, I will do this at the weekend, and is there anything else of a maintenance nature I should look out for?

Thanks
