Converting European RNS-E Units to North America
Instructions and tools for converting EU RNS-E to NA units.
Please note that converting units and performing a PRG Clear, as with any firmware update, is not without risks. These procedures have been tested on EU 192 and 193 models. However we advise that you undertake the conversion process entirely at your own risk.
Converting 192 Units - EU -> NA
Loading the NA firmware to a EU unit (or indeed probably EU to NA) is easy. Simply use the Engineering Mode PRG Clear function:
- Insert a CD or map DVD containing the required alternate region firmware*
- Perform a PRG Clear
Converting 193 PU Units - EU -> NA
Converting 193 units is slightly more complex and requires special update CDs to be prepared. We provide a selection of ISOs here to perform the conversion process.
Note that a converted unit will still have the boot loader of the original unit. As such if the boot loader's recovery mode is ever triggered (following a bad flash or PRG clear for example) it will require a special hybrid recovery CD.
Covert EU -> NA
Use this procedure for an initial conversion. The firmware present in the update is the last official release from Audi for NA units: 0230
After upgrading standard NA navigation media and firmware update CDs can be used. However note the waring above about performing a second PRG Clear.
Revert converted unit to EU
Use this procedure if you ever wish to convert a unit back to original EU firmware. The firmware in the update is the last official release from Audi for the EU units: 0220
Standard EU navigation media and firmware update CDs can be used, and a PRG Clear can be recovered with a standard EU firmware. No need for the special recovery firmware below.
Recover converted EU unit to NA
Should you ever find a converted unit which is stuck in the boot loader emergency recovery mode* ("Check DVD" or "Insert Original DVD" screens) you will need a recovery disk.
* Note: This can be the result of performing a PRG Clear on a converted EU unit in NA mode. It can also happen as a result of a bad or incomplete software update on an unconverted unit. On unconverted units use a regular navigation DVD or software update CD to perform a recovery.
Converting 193 PU Units - NA -> EU
Probably this is possible, but we don't have any genuine US units to test with. If you'd like to help us investigate please drop us a line.
