Had a sat nav fitted to my 03 plate 2.6 V6 which does not even recognise the M6 toll road, can you just get a new cd? Assume it cannot be updated to read post codes?
Better off switching it off and using a TOM TOM 
Sadly yes, i use tomtom on a mobile phone, and the Mrs Tomtom one on occassion, far more often for ease of use not to mention cameras and
Traffic which is important to me when commuting on the M4.
However when it comes to actual guidance the car system rules by a country mile. Tomtom can let you down and loose signal in built up areas on cloudy days, and can take a good 5 mins to locate from cold.
But i suppose between the two they cover most situations and eventualitys. Do feel a twonk on the few occassions i've had both on. Usually in London trying to get out. Cursed place, need all the help i can get.
Which reminds me, i have an idea to run the tv out from the mobile to the colour screen somehow, then voice activate stuff like tomtom to the cid.although i may be the only one who thinks its a "good" idea...
Need some serious help from some very busy admins who have far more know how than me to sort it out though....
