Well, I have mixed feelings about it. Note that I have only been testing it for a few weeks. I recently used it for navigation in the car. It did its job, but I was amazed how slow it is when you type in an address (lag time between keystrokes). On the bike, a little brighter display may be good but it should be okay. I am still trying to find a good spot for the GXM antenna. So far, attached on top of my tailpack with velcro does not provide good reception. Using the magnet on the side of the tank (although not recommended by Garmin ) seems to perform best. I think I need to provide enough cable slack to mount on either side of the tank to get the best possible view of the southern skies. The sound quality and volume of XM sucks when paired with the scala G4. I am investigating how that can be improved. Let us know your thoughts when you get to play with yours!
