The product is good and has all the features of similar car navigation kits but I thought the instructions provided were very basic and inadequate; does not answer many of your questions. Trying to fit it on my bike a Honda CBR600F (popular model) was a nightmare, ended up buying two extra mounting kits and the third one worked (one provided with sat nav did not work). The instructions on how to mount the system should be much better or tell you who to ask/where to buy another mounting kit, and poor instructions on using the headset, how to recharge etc. After four weeks of waiting for mounting kits to arrive in the post, I got frustrated at not being able to use the product. It is working now, but an annoying experience.
