UPDATE I HAVE MANAGED TO GET THIS WORKING. READ MY NEW POST FO INFO. After searching several sites and wanting many YouTube videos, I have still not been able to get a definitive answer to weather the iPad (wifi) will work whit the tomtom car kit external gps. Since I could not find out the answer I have decided to test it for myself. I already have a tomtom iPhone car kit and I went out and purchased an iPad with wifi. The first test involved plugging in an iPhone dock extender cable in from the tomtom car kit to the iPad. This test was unsuccessful, whilst the iPad did recieve power from the tomtom car kit, no data was transferring from the cable. After plugging in my iPhone this way, I was able to confirm that the cable was to blame and I still had hope that the tomtom car kit would be compatible with ipad providing it was directly attached. In my next test I completely disassembled the iPhone tom-tom car kit, as the ipad does not fit onto it normally. After disassembling it I was able to remote the dock connector from the housing and plug the ipad into it. Shortly after my iPad displayed a message stating that "this accessory is not compatible with ipad". After doing these two tests I have concluded that the iPhone tomtom car kit is not compatible with the apple iPad (wifi). Whilst this is disappointing, there is not a lot I can do. I hope this can answer anyones question to weather the tom-tom car kit is compatible with the ipad and sadly the answer is NO. If anybody knows of an external gps receiver that is compatible with the iPad and tomtom navigation application then please let me know.
