Hi,
Sorry Xenon for a very late response I seem to only get notified of responses if I have started the post so I will have a look in settings to see if there is a box I have not ticked to get notified if I have chipped in on someone elses post.
To the best of my knowledge now there are basically 4 satnavs that were made for the early cars for fitting into the dash mount 68R slot. Then also some of the later TomTom models were made available with cable&screen suction mounts if no 68R.
The first was the magnetimarelliMAP Blue&Me with microsoft/chrysler and IMHO is useless.
Next came the first TomTom (basically a TT (one) similar to the XL but partnered with chrysler added software spec) so with Blue&Me integrated feature. This was quite good albeit graphics now would appear a bit dated but had its own exterior SD card slot to update or change maps. This was silver and had its own CRATT unique cradle for the dash 68R or could be fitted with cable and screen mount if car had Blue&Me but no 68R slot. Basically the 68R slot was just a 12v power supply and the voltage conversion was done inside the cradle.
Then the TomTom2 Blue&Me with all the LIVE services came along and with vastly improved graphics with lane control, overhead road signs and even buildings and trees and stars in the sky at night. It also came again with its own unique cradle known as CRATT2 but appears two different designs are available one with a front release and the other with a side release. I have not fully established this as only seen pictures of the 3 TomTom cradles but these are the only two compatible ones for TomTom2 and generally whilst ALL models including MMMap fit the same 68R dash slot the cradle themselves are then specific to the satnav model. The TomTom(one) cradle has noticeably round finger pushes on the side where as the TomTom2 has square ones
Yes basically the TomTom2 is a 4CS01 model which is a TOMTOM GO LIVE 1000 with a 4.3 inch screen. It is much slimmer and neater than both the previous models and achieves the larger screen by a smaller surround. Originally came again with Blue&Me but then I believe TomTom or Fiat realised there was a small hole of a market for those cars that did not have Blue&Me but could have a 68R dash mount fitted so the same model was launched without Blue&Me but loaded with the Chrysler marques and graphics of all the cars and vans in the range. This provided nothing else for interacting with the car but the TomTom had its own voice command and BlueTooth phone linking.
Regarding size you can just squeeze into the cradles the TomTom GO 1005 Live which has a 5 inch screen but you cannot get this model with the integrated Blue&Me software.
We have successfully now updated early cars 2009 onward and installed the TomTom 2 updates up to a 2015 500 model and done two 2012 Alfa Mito's. As of yet not tried anything around 2007/08
When I say we it is my software engineer who has managed to decode the BMConfig files which are then uploaded back onto the car through the USB port to tell the car it has a TomTom2 installed and not a TomTom(one) or the original MMMap.
It was 'Touch & Go' as the main Fiat dealer said it was not possible:bang: and when during the update to the car the radio suddenly splurted out in Italian

we looked at each other and just laughed as honestly we figured we had just screwed the cars software. That said suddenly the message came up update completed. We then fitted the TomTom2 and paired it to the car and all was well.:yum:
To be honest we all like it although the screen is smaller than later inbuilt models it is better suited in line of sight and allows the cars data much easy read with graphics on the TomTom screen rather than what just comes up on the speedo cluster.
Secondhand ones now selling from £50-80 on ebay it really is a good investment and if anyone has the old MMMap really is a fantastic improvement.
I am more than happy to be corrected on anything written as certainly not a specialist, just bought a car for the daughter a few months back and been bored during the lockdown isolation so finding things to do:worship:
