EDGE ST

I have been using the EX for about a month and it is spot on. Absolutely no Issues. Using it with a windows laptop. Also have the MX 'bluetooth' unit. Use it with a Kindle fire for dashboard. Usually have a problem connecting, but once connected it is great.I don't blame the MX, it is probably something I have set incorrectly. I have to go into settings and check that it is set to bluetooth and then it connects. That's my two cents.
