POI .gpx Editor for the Mac platform?

Hi Everyone,

Does anyone know of a POI Editor for the Mac platform, that will parse .gpx files and correct any XML formatting errors?

At the moment I'm using MacTools "csv2gpx app." but the resulting .gpx file won't upload to my Nuvi 670. I'm forced to manually add lines of XML code to the file, to make it aceptable for the Garmin's Mac POI Loader, to upload it to my GPS unit.

Thanks for your time.

Regards,
