Gil,
I did carry mine for about a year and experimented carrying/mounting in different locations. At first I had the early large model with suction cups that was windshield mounted. It scared the heck out of me thinking I would loose it, or it would just fall off. It never did. I did not want it visible to others so I next concealed it in my windshield pouch/bag not knowing if the signal would transmit through the leather pouch, it did every time, no problem. I then received the free upgraded tiny version and experimented again tossing it into my side hardbag, again no problem transmitting. Now it's in a drawer somewhere and I registered all my plates. If yours works as well as mine you should have no problems no matter what location you choose. I hope this helps.
