Have found it difficult to find any OBD 1 scanner let alone a bluetooth variety. Was lucky to find an Actron III self contained unit 10 years back. OBD 1 ended production around 1995 about 30 years ago so the market for these type of scanners is very small. Highly doubt that any new OBD 1 scanner products will be developed. Your best shot is to find a used OBD 1 scanner and not all of them can scan all vehicles.
