CDC, Phone and Nav are enabled but not yet installed. PCM was retrofitted (previously a CDR-24). Car always had Bose, from factory.

Questions;

- Why are the targets all '/'?

- Why would the Amp not be entered? Is this a PWIS setting? As mentioned, it was always on the car.

- If I were to carry out an update to Level-A\2.1 software how would the update process handle entered, but not found items? Would it just skip them?

Thanks! :)

The level A to level B update only changes the System , PCM and in some cases Phone software levels (only if phone is configured). The blanks suggest that the other items are not connected on the MOST ring or are in the wrong sequence. THe software level you posted corresponds to level A , but the simplest way to determine if your PCM needs a level A to B update is by looking at the software version on the top title banner when Main and Trip are pressed together. If the number is below 3 ie 1 or 2 then you need an update. If the PCM is a very early version , it may require an update to level A before being updated to level B. As your Amp is listed as 017500 it should already be at level A as 017500 is not compatable with the level below version A.

As this is a retro fit you also need to consider the Navi drive , this part needs to be matched to the PCM , and should be updated directly after the PCM. This is done by using another update CD in the nav drive followed by using a later navigation Map. If the navi drive is not a matched part you need to understand what part it is and what level of software PCM its designed to work with.

THe PCM for some reason does not appear to be configured for the Bose Amp hence the value is not enetered. This can be configured using the PWIS.

If you plan on doing this update let me know , I've done it a few times including my own car.
