This particular one is from Garmin to use with their GPS. Probably common as dirt, but I'm about 15 years behind the curve on things digital, so it was news to me. Seems pretty cool, tho.

It's OBD-II only, so not usable in a Fiero unless you're running an OBD-II swap.

That, and I believe the common Bluetooth dongle with the best functionality and reliability is the ELM 327

I'm fairly certain an OBD1 bluetooth adapter doesn't exist. I'm sure with heavy electronics and software skills, one could modify a 327 for use on OBD1 application...

I believe that there was one made specifically for the Fiero style obd1:

Looks like it is still available.

Most of the bluetooth OBD-II dongles that are labelled as ELM 327, actually aren't. They are knock-offs.

I've found the best option to be the OBDLink MX. You can get a bluetooth or wifi version. It supports the full ELM 327 command set, and supports the full transfer speed for OBD-II CAN, which is about 4x faster than the ELM 327. It's $99 though, instead of $9.

There are a couple of GM ALDL pre-OBD-II bluetooth adapters available, but given what information is available, speeds used, and that you can't really drive the car with the ALDL in full use, they aren't that useful, either.
