TN555 Demo glitch and overheating
Purchased MOTONAV TN555 as Father's Day gift for use during rental car travel. Unit will switch to a DEMO mode after random periods of use thereby losing current search/directions. I went through the menu as best I could clicking and viewing all features as to 'check the box' of new ownership rules/regulations. Finally, resorted to utilizing the 'Reset' option returning the unit to factory settings. Currently waiting for the most inopportune moment during travel when the DEMO mode will once again appear and clear the saved trip/directions. Unit is out of warranty/return window by one week (of course). I have concern that if I sync his contacts (again) the unit may also 'react'? Additionally, the unit seems to nearly overheat after a bit of time (hour or two) and wonder if this is precipitating the malfunction? Any information/directives from experienced owners is greatly appreciated as 'we own it now' and are less than experienced ourselves. Thank you!
