HM55B doesn't use any standard inteface. I had to use bit banging.
I wouldn't recommand using it. For some reason I was getting a extra bit when I was doing bit banging.
Using compass with I2C or SPI interface would make your life much easier. :)
I was in real hurry and I'm sure my code had lots of bugs. Only had about a month to do coding.
Although this was a group project (my group had 3 people), I was the only one actually working on something. :(

Sweet bot, i like the diamond plate chassis! Cool idea with the wireless link also. Too bad about the slow updating. I have also used the Maxbotics EZ1 Sonar sensor on one of my robots and was able to update very quickly (every 0.5 seconds i believe) so your issue may very well be in the code as you suggested.
How did the Hitachi HM55B digital compass work out for you?
