I've got an Android head unit, but its got no satnav app on it.  I've been looking around but am not sure what's best for UK roads.  I had Sygic Fleet on a WinCE head unit, which was quite good, but there are two Sygic android apps; 'Car Navigation' and 'GPS Navigation' and I'm not sure which is right for a headunit (as opposed to a mobile).  Sygic Fleet doesn't seem to exist on Android and I hear that Sygic is expensive. I want an app with offline maps, so that rules out Google and Waze.
IGO and Copilot are possibilities, but I'd like to hear some UK opinions before I buy and install them. Like are their UK maps comprehensive and how good is their routefinding? Do they understand full UK postcodes?
Anyone out there got any recommendations? 

Waze and google maps are both great.

 

Not sure if they will work on your headunit though :/

Sygic GPS Navigation is for loading onto your phone as a stand alone SatNav. 

 

Sygic Car Navigation is for Android Auto. I would  email Sygic and find out if it is compatible with your Android head unit, rather than loading it onto your phone and then having a cable attached to your phone and head unit. 

 

For what it's worth, I use Sygic GPS Navigation on my Samsung S7 and it's great. Lifetime map and live traffic updates cost me around £30-35, and there are regular updates throughout the year. 

 

Last week it took me on a 30 minute detour around the M8, but that was far preferable to sitting in stop start traffic for over an hour. 

 

Sygic normally gives a full access 7 day free trial of their products for you to see if it is suitable.

I have Sygic on my phone, bagged it last year for about £18 when they had a deal going (worth getting the free version and keeping an eye on your emails  ). I now have a cheap ebay special double din which uses igo navigation (Tom Tom based) which is pretty good to be fair. Only downside is that the screen in the Mk 1 is a bit too low, so tend to stick with Sygic on my phone and keep it at eye level at the bottom of the drivers A pillar.

With Google you can download areas for nav onto SD card. Should be able to do it on android head unit like on phone.

OpenStreetMap for Android (OsmAnd+). 

Offline navigation with free map downloads for the whole world. 

Waze spends just ~200Mb a month, cant't believe that can be huge problem now days

even on abroad trips i prefer Waze and Google Map as backup,

have also loaded planned countries in Here, but haven't open it in last two years

 

 

@FIN69 I took your advice and emailed Sygic to see what they'd recommend for my unit.  They finally replied after 10 days just to tell me I should load both their products on my head unit and see myself which worked best...   Duh, thanks a lot!  Not impressed with their customer service. 

The issue is I have the head unit on a bench setup atm, and the idea was to load the apps now while I have connectivity before I install it in the car when I won't have easy internet access any more.  So testing these apps isn't practical and I just wanted to install something that worked when I put it in the car.

Sorry, rant over.

I used CoPilot on mine for ages, but switched to Google Maps for the traffic etc. I just switched my phone's hotspot on so it had internet.
