Hi! I’d like to make sure I understand your issue clearly. You’re trying to use the Carmin app on your iPhone with iOS 18.6.2, but when you open it in a web browser mode, it doesn’t load the app interface as expected; instead, it just shows a file that ends with the extension ".svgz"? Is that right? Also, could you let me know which browser you’re using on your iPhone to open Carmin in web browser mode?

This will help me guide you better on what might be going on and how to fix it. Generally, an .svgz file is a compressed SVG (Scalable Vector Graphics), which some browsers might display as raw code or download instead of rendering properly when there's a server-side or app issue.

Looking forward to your response!

The browsers showing file as raw code. Message that says wrong format

Thanks for the extra details! Since your iPhone browser is showing the Carmin app page as raw code or an .svgz file with a "wrong format" message, it indicates the browser is not interpreting the file correctly—likely because it received compressed data it can’t display directly.

Here are some steps to try on your iPhone with iOS 18.6.2:

1. Clear Browser Cache: Sometimes cached data causes this issue. Go to Settings > Safari (or your browser settings) > Clear History and Website Data. Then reload the Carmin web page.

2. Try a Different Browser: Safari usually handles these files well, but if you’re using an alternative browser, try switching to Safari and vice versa to see if it resolves the display issue.

3. Ensure You Use the Correct URL: Double-check the Carmin web app URL. Sometimes accessing the wrong link or an outdated bookmark can trigger file download instead of proper page render.

4. Disable Content Blockers: If you use any ad blockers or content blockers in your browser, temporarily disable them as they can interfere with how the page loads.

5. Update iOS and Browser: Your iOS 18.6.2 is fairly recent, but ensure your browser app is updated to the latest version.

6. Use the Dedicated Carmin App: If available, the dedicated Carmin app usually gives a smoother experience than web browser mode.

If after trying these the problem persists, it might be related to how the Carmin app server is serving the data—sometimes server misconfigurations lead to incorrect content types sent, causing browsers to misinterpret file formats.

Would you like me to walk you through these steps, or have you tried any of them already? Any info on which browser you’re mainly using would help me narrow down the best next step!
