No...they are not ALL the same for 2005/06 and that's because there are BMWs from old and new generations produced during those years.

The e53 was an old gen BMW still being produced at the time that uses the I-bus to communicate. Some of the new gen BMW models like the e60/e65/e66/e70/e90/e83 that were being produced in 2005-2006 could be using the newer communication bus (like the MOST bus) which is designed to handle the emerging newer technology.

For example, you can see the info on the two BT TCU units below...it clearly states on each one which type of commmunication bus it was designed to operate on:
