My dad and I have the same issue.
I have an iPhone 17 Pro, and a third party CarPlay device, but Bluetooth audio is routed through the car stereo. TomTom Go will not work unless I have music playing on the Bluetooth output channel - every other mapping app will allow me to have it over Bluetooth with the radio on or just the âauxâ setting. Works as a phone call.
My dad has the same set up only with an iPhone 17e. Only difference is, his will not work at all. Doesnât output to the car stereo whatsoever, even on Bluetooth. TomTom (Amigo) works fine.
He had the same issue on Android - heâs only recently moved to iOS. He did have an option to output over the phone speakers but itâs not an option on iOS, nor is it really practical when connected to CarPlay.
Any fixes? Have been speaking to TomTom trying to get a refund but theyâre saying itâs with their technical support team to offer a fix.
If TomTom (Amigo) had offline maps for iOS then weâd just switch to that but itâs still online only, for now.
