Re: BMW nav IV(Zumo 660)
Hope this helps.....
Comparison with the Garmin ZUMO 660
• • The BMW Motorrad Navigator IV is based on the Garmin ZUMO 660. Consequently, the two share same basic hardware and software.
• • Different appearance on account of different housing colours (Navigator IV black, ZUMO 660 silver) and the different font panels (removable). Customers will not be able to tell at first glance that the Navigator IV is based on the Garmin ZUMO 660.
• • It is only for the BMW Motorrad Navigator IV that the Advanced Mount Cradle with its array of 4 pushbuttons works, making the unit much easier to use while the motorcycle is on the road. Both units share the same method of attachment. The Garmin ZUMO fits into the Advanced Mount Cradle, but the 4 pushbutton controls do not work for the Garmin ZUMO. The BMW Motorrad Navigator also fits the Garmin mount without extra pushbutton controls and its full built-in functionality is available in this mount.
• • Only the Navigator IV can be used with the connecting cable to connect it directly and easily to the BMW Motorrad OA socket and thus to the motorcycle's on-board power supply (waterproof plug). Once the unit is connected in this way the built-in battery is kept continuously charged (applies only when the Sat Nav unit is ON). The Garmin ZUMO 660 connects to the power supply by cables with open ends (inline fuse); customers find this a lot more complicated and sometimes beyond their abilities. Use of the BMW Motorrad connecting cable is no longer possible for the Garmin ZUMO 660, because the cable is permanently connected to the Mount Cradle.
• • In principle, the two devices use the same software. the BMW Motorrad Navigator IV has a BMW Motorrad start screen and incorporates the BMW Motorrad dealership database. Uploading the BMW software to the Garmin ZUMO 660 will not damage the unit, but exclusive BMW functions remain unavailable (along with the start screen and the dealership database, this includes Bluetooth data interchange between two Sat Nav units and the functions of the Advanced Mount Cradles).
• • The audio port (on the left in both cases) is covered in the case of the Navigator IV by the Advanced Mount Cradle; in the case of the Garmin ZUMO 660 it always remains accessible. This audio port, however, is not needed on the road for the communication system offered by BMW Motorrad, because audio signals are transmitted by wireless via Bluetooth. During breaks, headphones can be connected to the audio ports of both units, as that the built-in MP3 player can be used. The Navigator IV has to be removed from the motorcycle mount in order to be used in this way.
• • Both devices have an audio jack on the cable set of the (Advanced) Mount Cradles for connecting a wired intercom system. The ZUMO 660 outputs sound in stereo, the Navigator IV in mono quality (perfectly adequate for voice). Only the Navigator IV has a connection that remains permanently waterproof.
• • The Garmin ZUMO 660 has an additional port on the cable set of the Mount Cradle as the input for a microphone and a mini-USB port. Neither of the two are permanently waterproof.
• − The Navigator IV does not support an external microphone on the motorcycle. Using handsfree for phoning with the Navigator IV and a Bluetooth mobile phone while riding a motorcycle requires a Bluetooth-compatible helmet (does not apply to in-car use; the built-in microphone in the Navigator IV is used along with the built-in speaker).
• − Unlike the Navigator IV, the Garmin ZUMO 660 has a mini-USB port in the wiring harness for an optional TMC receiver. Neither the port nor the TMC receiver itself are waterproof. Use of the TMC receiver on the motorcycle is expressly prohibited. This is the reason why the Navigator IV dispenses with a connection of this nature. For in-car use, both units can be connected to the in-car mount and the TMC receiver used in this way.• The ZUMO 660 comes complete with a universal motorcycle mount; the Garmin instructions for use state that extra hardware might be necessary for user-specific installation. The Navigator IV needs a motorcycle-specific mount, optimised for each model, that has to be ordered separately.
