I thought I will add my notes and tips how to upgrade the SMEG+ telematics unit on the Cactus.
If your car does not have satnav or DAB options from factory there is a way to upgrade the SMEG+ unit.
First new SMEG+ unit is needed. Be aware that some of the units sold on Ebay have despite the description no Satnav or DAB option. One way to identify the satnav unit is to look which connectors it has. Satnav units have always blue antenna connector in the back and DAB units have brown one. White and gray connectors are standard FM1/AM and FM2. Here is the full option Cactus SMEG+:

If there is no picture from the back but is a picture from the label it is also possible to identify the unit. The important numbers are level number and software number:

You are on the safe side if the new unit is H1 or H2, the latter has in addition to satnav also DAB. The software number has to begin with 5. Other softwares are 3.XX.X which is older firmware and 6.XX.X which is SMEG+IV2. I think it is possible to install a unit with older SW but who wants older units, the SMEG+IV2 can not be installed as far as I know. The reason is that all the cars that were originally equipped with it have separate climate control buttons so it lacks a possibility of touch screen climate control configuration. This is the unit which also has Apple Carplay unfortunately.
The equipment levels are described in this document: https://fccid.io/ANATEL/00719-14-05386/MANUAL/DADF0ABD-43AA-405C-8165-C6B5BEC8D0EC/PDF I have seen levels not described there so it is not a complete list but as far as I know Cactus was equipped with units B1, B2, H1 and H2. My original unit was B1.
If the unit is bought the installation itself is a piece of cake. Remove the passenger side lower trim, unscrew the two torx T20 screws, disconnect the connectors, connect new unit and put the screws back.

Next it has to be coded to the car so the VIN stored in the unit matches with the one stored in BSI (Built in Systems Interface). Until then it works but makes a beeping sound even when the radio is switched off. Also the navigation menu button has to be configured to be present on the touch screen. This all has to be done by the dealer (around 50 euros) since there is no option to configure SMEG+ nor touch screen with unofficial Diagbox and clone interface. I think it is possible to install a unit from Peugeot also but then there is in addition to VIN configuration the need to download the appropriate Citroen profile from PSA servers.
Then the only thing is the antenna. It is reported that the simplest GPS antenna for a ten or so euros/pounds from Ebay works perfectly fine placed under the dashboard. The original antenna base and cables do not cost a fortune also (about 100 euros in all) and there are these antennas on Amazon: https://www.amazon.de/s/ref=nb_sb_noss?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&url=search-alias%3Daps&field-keywords=kombiflex+antenne The problem is however that it is very difficult/impossible to install a new antenna base without removing the roof liner. I therefore went a different route and bought this kind of antenna (there are black ones also): http://www.scan-antenna.com/product/satfix-1-gps-white It has to be active with 5V phantom supply because SMEG+ applies 5V to the antenna.

It has an FME-male connector so I ordered 5m RG174 cable from the local radio shop with FME-female connector in one end and Fakra blue connector in the other. RG174 coaxial cable is used originally also. I routed the cable under the right edge (my unit is in the right side) of the roof liner and installed the antenna into the rear spoiler:

The spoiler is attached with six 10 mm bolts and with some clips. Unscrew the bolts and pull the spoiler off:

Small section of the inner part of the spoiler has to be cut off in order to make a hole for the antenna mounting. It is the only center point.

The FME-female connector is thin enough to go through the rubber boot of the trunk hatch. Then route the cable through the existing rubber boot on the spoiler or make a new hole (the hole has to be sealed) for it.

Since the spoiler is not completely waterproof from underneath I put some silicone into the hole of the antenna mounting where the cable comes out.
In order to get better access under the roof liner the c-pillar trim has to be removed. To do that the black pieces have to be removed first then it is possible to remove one screw from the white trim pieces. The roof liner has two plastic clips in the back also which are easy to remove. Then you can pull the liner downwards a little.
So all done and 12 satellites visible

Total cost: SMEG+ - 275 euros (with shipping), antenna 25 euros, cable with connectors - 10 euros, configuration by the dealer - 48 euros = 358 euros
