Blue an me was obsolete within a year of launch back in 2006, when only a year later Apple released the iPhone which was not compatible with it and completely changed the future of smart phones, then android came along, also not compatible and fiat basically had what had been a very promising and expensive technology to invest in and develop and no viable replacement.
The is no safety issue with it so they would never do a recall.
the last cars to have blue and me are now well over 9 nearly 10 years old so there is no incentive for fiat to do anything at all about it. They stopped updating it following the last update to the underpinning software in 2010 (Microsoft windows embedded automotive) Microsoft ended support in 2016, fiat carried on allowing people to down load updates till 2021 when Adobe Flash support was ended (this is the technology used to run the Blue and Me update website) then in 2022 the website was taken down all together. So there is no incentive for anyone to keep using it.
you will need to find the module in the car and unplug it and remove it.
then get the appropriate adaptors to fit an after market radio. While there are normal ISO connectors behind the radio in every fiat the connections are not compatible with aftermarket radios and you will need an adaptor.
you'll probably need a faceplate as well to fit an aftermarket radio.
Then you'll need to get the blue and me module coded out which can be done with the registered version of
MES for about £50. and another £tenner for the cable. This is money well spent as it will allow you to check your car for faults and clear faults which is very handy as most garages will charge £50 or more just to look at and clear fault codes.
Well worth doing, no rush to have to spend a fortune all in one go. I would probably get the B&M module disconnected at the very least as when they go bad they can caused a drain on the battery of the car leaving it drained and you unable to start the car in a morning. the radio in the car will continue to work as a radio. Then you can look at whats needed for the replacement radio, wires, face plate etc.
When you take the old radio out, there should be a sticker on the top which the wiring connections on it for the radio, Take a photo of it, you will need that photo when you come to install the new radio.
