Good points: - Overall good quality product. - Replaceable battery (Nokia standard model). Negative points: - Has never been able to connect to the TomTom Navigator software (version 6) on a Palm Treo 680. This is not a Bluetooth connection problem, since it works with other software operator GPS info (4 Pathaway the hike). I reported the problem by email to the technical service Qstarz, who never answered me.
