aumandg,
Since no one has offered any help, I give you my two-cents of advice...
I DO NOT KNOW if the update will work via Bluetooth. But this is how I do it...
The safest way to upgrade the firmware is WITHOUT BEING ON-LINE. This prevents problems with internet connections failing in the middle of the upgrade process, resulting in the need to reset the firmware (999).
Download the file (rom file) from Meade and extract it into the Meade\Autostar\updater\ephemerides directory on your laptop.
Using ASU, just load it directly into your scope (the source will be the above folder NOT the Internet).
I personnally think that Starpatch does a much better job at updating the Meade.
Starpatch is free (for the LX200 GPS) and can be found here:
