I have been following this TomTom & N70 issue and have been carrying out my own tests, which I will go into detail on now to try and draw up some conclusion as to who the fault really lies with..
I will start by listing my firmware and driver versions etc:
My N70 is unbranded � Firmware V.20.0536.0.2
12-09-05
RM84
Bluetooth Receiver � BT77
TomTom APP Version - 5.2 (Also tested with 5.0)
GPS Driver - 1.20
I have experienced all the same problems as everyone else, frequent connection lose between 5-10 minutes which requires a reboot of the phone before connection is established again!
I have tried all previous suggestions such as offline mode, delete pairings from the bluetooth list etc but none of those have fixed the problem.
Here is what I have found:
Connection is maintained if you are not actually travelling in the car. I tested this by leaving my receiver on the window ledge over night. When I woke up next day it was still connected.
However, if you plan a route (I did my 36 mile commute to work) and set it running as �Show Route Demo�, it crashes whilst running the demo, the connection is lost but then the demo continues. This happened time and time again with varying lengths of time, sometimes 10 minutes others 2 minutes!
So next test was to see if the demo would run crash free when the bluetooth receiver was not switched on. Again I set this up over night with the demo repeating. Woke up next day and the demo was still going, crash free.
At this stage I was now thinking that there is a definite fault with the N70 bluetooth, and set out to try and get my phone updated with the latest firmware from Nokia � V3.0546.2.3
Unfortunately I have been unable to get this done anywhere local to me over the past few days as the engineer from the carphone warehouse service centre is away until after Christmas.
So in the meantime I have been trying various other tests, and one which I think (repeat think) has been successful is if you turn off the map display. It is on page 1 of the preferences menu. So far I have not lost a connection this way whilst the phone has been running the demo. I will confirm this by leaving the receiver on my window ledge over night and setting the demo running.. If when I wake up tomorrow morning the connection is still established and the demo still running, then I think this is the solution. I know it�s nice to have the colourful map display but for now, as a temporary solution lets hope it works so you can still actually navigate!
I�m still none the wiser of who is at fault, but one thing I noticed while looking through the TTMOBILE.APP code from my old version 5.0 was this:
W h e n u s i n g t h e p h o n e , t h e m e m o r y c a n b e c o m e f r a g m e n t e d ( t h e a m o u n t o f f r e e m e m o r y d e c r e a s e s ) . T o s o l v e t h i s , t r y r e b o o t i n g y o u r p h o n e .
It is almost as though the N70 is allocating all its memory to the map display as it re-draws it when your moving? I would appreciate it if people having the same trouble could try out my suggestion and report back.
I could be totally wrong, but hopefully this will be sorted soon.. I miss my 6680 :frown: lol
