I've got an AUTOCOM. Does it ALL! No batteries to charge, just plug in and GO!!!!
If I were to replace it, or be buying new..... I do think I would go with the Scala G9. Supposed to be the best out there. Bike to bike, rider to passenger intercom, connect your phone, GPS, etc via Bluetooth, bump pairing, FM radio built in and works with either full coverage or half helmet.
