Saabnc,
I was told that they will email you if there is a "important update". In the 7 Months I have had stage 1, I have never had the email. When you log on you do get this from the BSR site :
Download:
This is a program for communicating with BSR database.
When there is important updates we will e-mail all affected customers.
You should only do updates if BSR contacts you.
This version number got nothing with your cars software to do.
PPC Update 1.5.10
My guess, and its only a guess,

is that its unlikely that there will be any "enchancments". The PPC has been around for a while, so any early problems would have been corrected by now..
Sorry your have problems XAAMOTTOMAAX
