There's no way to hook the Mk2 tuner up to the Mk1, I'm afraid. Sorry.

As far as the power antenna goes, that's a good question. Some radios have a separate control wire for the antenna, others assume that the amp remote line is sufficient. What's the word, Hugo or Rob? Will the Mark2 tuner have a separate antenna control wire, so that you don't raise the antenna when listening to MP3s?
