SOME SPECIAL NOTES FOR S32F0 USERS:

NavRadio cannot be fully integrate into the system without patching the carService.apk and to do this you need root access (eg. use Malaysk rom)

NavRadio can work without this patch but it require the original radio app to be running in backgroud and some weird behaviour can happen..

To patch the service i added an option in NavRadio settings that enable and disable the patch anytime you need.

Once the patch is enabled, you just need to reboot and everything will work better.

The only one thing that I still need to work out are the steering wheel commands Next/Prev that right now change the stations saved by the original app and not the NavRadio+ ones.

------------------------- SOME TIPS ----------------------

TOGGLE SCREEN NORMAL/FULL:

- Double Click on the station information toggle fullscreen on/off.

NORMAL SCREEN:

- Long press on the station information popup the "ADD Station" dialog window if the station is not in your station list. If it's already in your list, it will focus the relative station button.

- Long press on a station button bring up the "EDIT Station" dialog window

- Single press on screen arrows <> does a small frequency step fwd/back

- Long Press on screen arrows does a quick search fwd/back

FULLSCREEN MODE:

- A Single press of the arrows <> switch to next/previous station

-A Long press on station information(center of the screen) bring up the "EDIT Station" dialog window.

- In interface settings you can remove the big frequency in background if a logo is available.

- In settings you can hide status bar, activate the clock and a speed gauge

STEERING WHEELS CONTROLS:

- The steering wheels commands act exactly in the same way as the fullscreen arrows, they just need to be setup in the correct way in carsettings application.

FAVORITE LIST:

- The FAV list is the result of merging FM and AM favorites, so you can have both frequencies in the same list.

- FAV stations can be edited within the fav list but cannot be added. You need to be on fm or am list to add a station and set it to favs.

- Deleting the FAV list will just remove the fav flag from the fm/am stations but will not delete them.

- Deleting AM/FM list it will delete the FAV list too.

LOGOS:

- you can use your own station logos, you just need to know where you have them stored and browse for them when editing a station.

- To get the stations Logos from the app you have to set the nationality of the logos in the interface menu, download and extract them.

Once they are extracted you have to edit each saved station to assign the logo image to it.

- The automatic assignment of the Logos is based on the RDS id of the radio stations (pi code) and the search of the logo by RDS name.

The first method (by id) is faster and more precise but it needs that the name of the logo contain the picode of the station and for this purpose i renamed them for some of the available countries. Of course i cannot make them all and the functionality of this method depend of the availability of correctly named logo images for your country.

The second method (by name) is less accurate and it work comparing the RDS name with all available logos. If the rsult of the comparison is 100% correct the logo is autoamatically assigned. If the result are more then one logo, a dialog window popup asking you to choose it.

For USA and Canada the assignment of the logo is is done by searching the frequency of the station in the logo file name.

AF (Alternative Frequencies) handling: (Doubleclick to switch between stored AF)

AF service allows the radio tuner to tune in to an alternative frequency when the signal becomes too weak. The minimum level signal can be set in factory settings (Auto Search Stop) and has been found

that around 30 db is the best choice.

To improve even more this service I added an automatic storing of the alternative frequencies so that every time a new frequency is received, it's added in a list.

After an autoscan some radio stations can be found on different frequencies, NavRadio+ have an option (in Settings/radio) to automatically merge the frequencies in just one button populating the AF list

The frequencies available in this list can be selected using the station editor or switched one by one DOUBLECLICKING on the station button.

NOTES:

I'm the only developer of the app and I work on it every single day for some hours a day.

I try my best to develope the app at best of my possibilities and I wish at evey release that it is bug and crash free.

This is very hard to achieve, even if I have some very good friends that help me testing it.

I'm really thankful to them for their help and support.

Thank everybody who beleive in my work and thanks for understanding. :)
