Please enable direct connection of cellphone and GPS units to the SMH10, rather than a cellphone having to be piggy-backed through the GPS unit.
With the current set-up, it involves looking down and screen-tapping to commence or end calls, which is less safe. Direct connection of a cell-phone would permit voice-activated control and any other cellphone functionality, and make it a LOT safer and much more user-friendly.
This lack of direct connection is also not made clear in the information about the SMH10 that available to intending purchasers. It has to be searched out. I know that I missed it and it would have impacted my buying decision, had I known about it in advance.
