Yes you do!
With map contacts on, you basically have auto-plotting, with the exception that it doesn't give you GPS-accurate reading on composition and heading while you are still 20 miles out. Every contact, friend or foe, merchant or warship, uses the same square (zoomed out) or dot (zoomed in) symbol. However clicking that dot on the nav map reveals if it's a warship or merchant.
Yes, it's not the instant contact update you're used to but it's actually more exciting this way. You'll quickly learn not to pursue medium speed contacts of two ships (the usual ASW patrol)
At first I was tempted to turn off the map contact stuff in TM (you can - just read the documentation - and it only involves deleting a file from TM before installing), but after a few patrols I started to like it. It fixed the major annoyance related to no contact updates - TCing straight into a taskforce because the TC wouldn't drop back automatically on visual contact.
