Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suggestion
The system does run a little slower than the newest models, but that kind of obsolesence is unavoidable unless you want to upgrade every two years.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Could someone provide feedback on Porsche's PCM/Navigation System? Does anyone regret getting it or not getting it? How does it compare to other units? Is the system worth the $3-4K price? Thanks. b-man

POST 2Original post

slow, data base is poor, difficult interface, not able to turn off the Radio?cd and still have Nav... Only Plus: Duplicates the OBC and AC controls. I would get it IF you want NAV and an Factory original car, i.e. not Modified.

POST 3Original post

I've driven my PSM-equipped '99 across country twice (Seattle-Boston-Orlando-Seattle, Seattle-Phoenix-Vegas-Billings-Seattle). I have no regrets with mine. I very much enjoyed the system, and it works great. I wouldn't call the database poor; I found a few problems in one city (Charlotte, if I recall correctly), and thought it was a fantastic aid. It's a real plus in unfamiliar cities, and can even be helpful finding specific locations in your hometown. The system does run a little slower than the newest models, but that kind of obsolesence is unavoidable unless you want to upgrade every two years. Still, I can compute a route through two states in less than 20 seconds. The PSM's computer doesn't duplicate it the OBC. The features offered by the PSM are a superset of the OBC. .B ekiM

Mine came with a screwed up CD reader, parts ordered. Robin
